ABSTRACT: The use of a Dointillator with a connected multiplier in dosi- metric devices is to be recommended. The Russian multipliers FEU-19 and FEU-25 can be used successfully for such dosimeters only if it is possible, by some means, easily to obtain a stabil- ization of voltage. The scheme with the corresponding resistance- and voltage values is given. In the case of main voltage fluc- tuations of + 10% .- 15% the multiplication coefficient remains un- chRnged (up to + I ~) if this so-called selfstabilization is employed. In order somewhat to compensate the disadvantage of the small photocathode of Russian multipliers, a cone-shapad light con- ductor, which consists of severa2 cones telescoped into one an- Card other, is used. 0/' M - Mao 45, AUTHORS: Istomina, A.G., Keirin-Yarkus, I.B. 8C -1-1?,/18 TITLE: Ex-Deriments for the Determination of Maximum Acceptability of -hormal Neutrons (Opyty k o~bsnoraniyu predellno dopustizykh potokov teplorrjkh neytronor) FERICDICAL: Physics and Thermotechniques of Reactors (Fizika i teplotekhnika reaktorov), Supplement Nr 1 to Atomnsva energiya, 1958( USSR) ABSTRACT, The distribution of protons and d-doses vras determined experi- mentally on a paraffin model.

TITLE: The ILK-3 Individual Luminescence Dosimeter i,E,RIODICAL: Pribory i tekhnika eksperimenta, 1959, Nr 4, pp 74-80 (USSR) ABSTRACT: The apparatus is an improved form of one described in 1955 (Ref 1 - Session of the USSR Academy of Sciences on the Peace- ful Uses of Atomic Energy - available in English). The main new features are that an improved phosphor is used, and that a very much better recording circuit has been developed. The phosphor is not described in detail, but is a CaSO 4-Mn one. It is not sensitive to daylight, and so the badggs can be handled under normal lighting. Fig 5 shows how the readings decay with time after a single dose at various temperatures (given on the curves, top half of the figure; the abscissa is in days). The second half of this figure shows the effects of chan ing the temperature. Fig 6 shows the dose response curves ~I is for X-rays; II is for 60CO y-rays; the abscissa scales are in kr). The two parts of Fig 7 show the hardness response; curve 0 is for unfiltered radiation, while curves Card 1/2 1 to 3 indicate the thicknesses of the Cd filters (in mm); SOV/120-59-4-16/50 The ILK-3 Individual Luminescence Dosimeter the meanings of the rest of the caption are clear, (The abscissa is in MeV). F---g 4 shows the electrical circuit. The apparatus discharges the phosphor by means of a flash of infrared light; the resulting light flash is recorded by the photomultiplier and is integrated by the circuits to give the dose received. Fig 2 shows the shutter system used to insert the badges into the photometer head; Fig 3 shows that head.

For example the O'CO-Eup3m phouphor is used in the ILK dosimetry method. The present yu.;Or describos a study of the storage of electrons, their distribution in tra pr an3 of trip parameters in S rS -Eu,Sm. The author us ad the thermal do-axcitation (TO) method. Before experiments phosphor screens were h,,~_,ted to 400oC in order to obtain an initial state of complete do-oxcitition. Photo-excitation was produced using an SF-4 spectro- ohotometer as a monochr=ator.* Gamma-ray excitation was produced by Qo6O source. The TD curves of the phosphor excited with light of 440 ztL wavelen6tn are given in Fig 1. The saturation light aum was reached in 20 min, as shown by the upper part of Fig 1. The form of the TD curves is practically unaltered when the duration of exposure to light Is varied by a factor of 50, i.e. the form of the curves Is independent of tho stored light sum up to saturation. The same is truefor 'taxcit~---.ion (F16 2)-. In a later axperiment phosphor screens were excited SOV/51-7-3-15/21 Study of the Light Sums in the SrS-Eu,Sm Fhoophor (Communication I) with light of 440 M-~L vavelongth for 20 min and the TD curves were obtained in the next 20 min. Then the same screens were excited with 440 m-p for 20 min, Illuminated with do-exciting light of 630-1400 m1i wavelengths for 20 min and finally the TD curves -were reported (Fig 3). The difference between the first and the second set of the TD curves showed that the do-exciting light acts most strongly on the shallow levels and affects the deepest traps only to a very small extent. Fig 4 shows curves constructed from the data of Fig 3 and representing the ratio of the thormoluminescence intensity of an excited phosphor irradiated with do-exciting light to the intensity of emission by a phosphor not subjected to de-excitation with light. If the phosphor has traps with different sonsitivitioa to the do-exciting light the curves of Fig 4 should be stepped and the plateaus on these curves shodd occur at the positions of individual themoluminesconce peaks. In agreement with theory such plateaus are In fact observed (Fig 4) corresponding to peakB at 60, 100, 130, 160, 200, 250, 300 and 3200C. A second series of experiments consisted of recording of TD curves after heating the phosphor screens to high temperatures. Fig 5 shows the TD curves of a card 2/5 phosphor excited with a 1200 r dose of 2(-rays , which was then heated to a hidi temperature T (280-3380C) in 5-6 rain, hold at that temperature for 2-3 min and then rapidly cooled to room temperature. Fig 5 shows that SOV/51-7-3-15/21 A Study of the Light Sums in the SrS-Eu,Sm Phosphor (Coanunication I). the maxima of the TD curves wore displaced by this treatment to temperatures above 3000C and their half-width was reduced. Increa6a of the temperature (T) of this short heating from 3050 to 3360C did not greatly affect the displacement of the TD curves and the half-width of the peaks was practically unaltered. These experimenta prove th%t in the Srs-Bu,Sm phosphor there is a complex spectrum of capture levels and that in the phosphor which vas haated to a high temperature for a few tainutes levels of only one type razaaln populated, i.e. the curves of Fig 5 are simple 7D curves. Trap Parameters deduced from the curves of Fig 5 and in other 'Keys show that in the case of very dean traps, thermo- luminescence is a process with kinetics of the first order, i.e. the probability of repeated capture is small. Knowing the parameters of the deepest traps the exparimental curves can be analysed into their components rhich are simple M curves. The results of such an analysis are shown in Figs 7-10. From these figures the distribution of electrons in traps can be estimated. The proportions of electrons (no,) captured by traps of a given depth E, are show in Figs 7-10 in the form of vertical lines -with heights proportional to n0j. The trap depths were found to be 1.0, 0.96, 0.91, 0.85, 0.78, 0.72, 0.68 and 0.56 *V. Comparison of the curves obtained on V_ and photo-excitation show that on %-excitation the deepest Card 3/5 levels -~-;ith F.= 1.0, 0.96, 0.91 eV are filled most strongly, while levels 3 CTV/ 51 -7 -3-1-5/21 bvly of -the LiLht Sums In Une %Gej-~Zu,Sm Phosphor kGommunication I) ,.-.-ith 0.72 eV are practically unfilled and electrons are cotapletely abn wit frau very o haliow levels rith 6 = 0. 66 eV (this absence is luo to lo.-ces during excitation). The author discusses also the nrobibility of thermal liberation of captured electrons and compares it vith the change in the magnitude, of a flash omitted by an excited pho3lohor after storage for periods up to t-molve days (Fig 11). This ,phosphor vis used as the active element of ILK dosimeters. The author ,Ltg,,-c3t,,i that the increase In the dosimeter readinzs on lowering of tam~'oraturo Is due to an increase in the flash yield vhile the fall In the dosimeter readings on increase of temperature is due to quonching.

The Measuring Unit PERIODICALt Pribory I tekhnika eksperimenta, 1960, No. 5, PP. 35 - 40 TEXT: The following requirements were taken into account in the design of the instrument: 1) small size, light weight and portabilityl 2) the instrument should be supplied from 110 - 220 V mains as well as from batteries or accumulators; 3) the measuring meter and the electronic circuits should produce an error of not more than + 30%; 4) the measuring range should extend from 1/2 to 100; 5) the instrument should not be affected by atmospheric or climatic conditions. The resulting instrument is illustrated In the detailed circuit diagram of Fig. 1. The input device of the instrument is a photomultiplier which in connected to the electronic unit by means of a cable having a length of about 1 m. The multiplier is followed by an emitter-follower pre-amplifier, based on a Card 1/4 85339 s/12o/60/000/005/007/051 E192/E382 Universal Scintillation Radiometer RUS-3. Note I, The Measuring Unit high-frequency transistor (cut-off frequency of 60 Mc/s). The emitter-follower is followed by an amplifier-shaper circuit based on transistors r1TI2 and tin 3 - The first transistor acts as the pulse amplifier, while the second transistor performs the shaping of the pulse. The presence of the resistor in the emitter of nn 2 ensures that the amplifier is stable, The output pulse obtained from the shaping stage has a duration of about 10 jis and its amplitude is 7 V (when the supply voltage is 8 V). T'fte shaping stage is followed by an integrating circuit which is preceded by an emitter-follower (transistor nn4 ). The integrating circuit has three different capacitances which correspond to the ranges of 30, 300 and 3 000 pulses/see. The circuit is followed by another transistor stage which is connected to a microammeter which indicates directly the number of pulses per second. The upper portion of the diagram in Fig. I illustrates the supply sources for the instrument, The Card 2/4 85339 S/120/60/000/005/007/051 E192/E382 Universal Scintillation Radiometer RUS-3. Note I. The Measuring Unit photomultiplier requires a stable voltage of 1200 V. This potential is obtained from an oscillator based on a transistor, type Mr-6 (P3-V), and.a suitable transformer. This oscillator operates satisfactorily even with input voltages as low as 3 V. The current taken by it (at 3 V) is about 81 mA. The supply voltage produced by the generator changes by about 3% when the input voltage is changed from 3 to 10 V. It can be seen that the instrument can be supplied with battery voltages from 3 to 12 V; as regards the mains voltage,this can vary from 80 to 250 V. In order to cover this range of AC voltages it is advised that a ferroresonant stabiliser followed by a rectifier be employed. In such a system it is possible to reduce the voltage changes to about 8 V when the input varies from 80 to 250 V. Constructionally, the instrument is in the form of small units which can easily be withdrawn and repaired or replaced by new units. The overall weight of the instrument with a set of batteries is about 3 kg,, A photograph of the Card 3/4 85332 S/120/60/000/005/007/051 E192/E382 Universal Scintillation Radiometer RUS-3, Note I.

These neutrons are not easy to measure, and this is one of the reasons that up to the present time they are not taken into account in dosimetric practice although they often constitute a substantial part of the total neL-tron flux. The contribution to the absorbed dose Card 1/8 frcm. the intermediate neutrons is also increased due ~ `3~~3 Maximum Permissible Doses of Intermediate zn Energy Neutrons an(J Their Measurement to the fact that, Inturmedlate neutrolis afff2ct the organism more strongly than the i;hermal ones.

They com- puted the maximum permissible absorption dose assLLm- ing the relative biological efficienc, (RBE) for protons to be 2, 4.5, and 10. Results are on Fig. 2, The authors point out, however, that the maximum absorbed dose does riot always determine the biologi- cal effect of the radiation. The RBE is different for various kinds of exposure and depends on the reaction of the organism to radiations which may be in the form of prolonged weak doses, may vary at various depths of the tissue, or may consist of short Card 2/8 but very strong exposures.

Il. y- and P-Probes PERIODICAL: Pribory i tekhnika eksperimenta, 1961,Nool, pp.86-91 TEXT: The first part of this paper is given in Ref-5- In accordance with the design specifications for the WIC -3 (RUS-3) radiometer, the dose-rate range of the instrument should be 1-250 ILr/sec. This corresponds to a y.-ray flux between I .6 x lo3 and 4 x 1o3 y quanta/cm2see. In order to a--hieve the required accuracy of 1 30% at the lower limit, it is necessary -to record about 10 pulses over a time interval of -(.'= RC = 3 sec. it follows that the minimum recorded counting rate should be about 3 pulses/see and the efficiency of the probe with a 1 cm2 screen should be about 0.2%. Such a low efficiency can be achieved with an inorganic crystal of about o.i cm3, or a larger organic crystal. For practical reasons a polyerystalline stilbene screen (phosphor), 25 mm in diameter and about 150 mg1cm2 thick, was used.

The visible radiation is measured by a photo-electron multip ier type ,~__444-29 (FEU-29) which has an amplification factor of 10~, With the photo-cathode at a distance of 26 mm from the specimen, a cathode of 39 mm diameter observes 10% of the total solid angle and, because of reflection from a brass plate beneath the specimen, the proportion of solid angle actually recorded is greater than this. The equipment is screened and water cooled to avoid heating the photo-electron multiplier, There are 1 figure and 1 Soviet-bloc reference. SUBMITTED: April 3, 1961 Card 1/1 NEI - KkM, A.

It is a compilation of articles written by various authors on cosmic radiation, its sources, levels, dosimetry techniques, and physical methods for protection against radiation. The authorst purpose was to present the problem of radiation safety in space flight as fully as possible. Peculiarities of cosmic radiation dosimetry are outlined; radiation conditions in space, basic interactions of cosmic radiation with the matter, and radiation protection are analyzed. Chapters I and 3 were written by Z. B. Keirim- Markus, Chapters 2 and 4 by H. A. Sychkov, Chapters 5 and 8 by A. V. Larychev, Chapter 6 by Ye. Ye. Kovalev,.Chapter 7 by Ye. Ye. Kovalev and L. No Smirennyy, Chapter 9 by V. Go Bobkov, and,Chapter 10 by V. P. Demin and V. A. Sakovich.

ORG: none HTL'E': Measurement units used in ionizing radiation dosimetry and radiation safety equipment SOURCE: Izmeritel'naya teklinika, no. 11, 1966, 18-19 TOPIC TAGS: ionizing radiation biologic effect, relative biologic efficiency, radiobiology, x ray radiation biologic effect, radiation shielding, radiation safety.1 radiation dosimetry ABSTRACT: Tile authors criticize COST 8848-63, adopted 1 July 1964, which established! joules/kg and coulombs/kg as standard units for measurement of ionizing radiation absorbed dose and exposure, respectively. In so doing, this COST standard ignored the decision of tile ICRU (International Commission oil Radiolorical Units) to i recommiend the use of the rad (-I centijoule/kg) and roentgen (=0.257976 milli- coulomb/kg), which are the units in which almost all presently used instrumentation i- is calibrated and almost all current research expressed. T1'c cumbersome numerical data conversions 'required by use of the GOST units will afflict not only all stur ies involving absorbed doses expressed in rads and exposures in roentgens, but also all biological shielding calculations containing equivalent or effective dose units (ber, rem) based on rad and roentgen. Indeed, COST 8848-63 provides no units whatever 1/2_-_ UDC: 577.391(017) ACC NRt AP7000129 for tile measurement of dose equivalents. The authors propose that COST 8848-63 be revised to establish the generally used and ICRU-recommended units of rad, roentgen, and ber as standard units, and further suggest that any new units for radiological measurement should not be officially adopted by individual countries unilaterally, but proposed through and approved by the ICRU.
