After considering the problems pertaining to (a) the dosage of tracer atoms in investigations on the metabolism of the nervous svstrm, (b) mett,nds of reporting the t?esults obtained in this type of work, and (c) extension of the use of isotopes in biochemical research, the coordination meeting made the following decisions: 1. The dosage of r~dioact.ive substances used in investigations of brain metabolism must correspond to the characteristics of the substance being in- vestigated and to the physiological problems subjected to study. ALthough a minimum quantity of the radioactive substance must be used, the dose must be large enough to yield ^t least twice the number of impulses produced by the backgt?ound when samples are examined- A desirable range is five to six times the number of impulses produced ley the bacY.ground. 2. To achieve greater p:?ecision it work with radioactive phosphoc?us, block or ens cs~urtilintion?J counters must ucncet orth be used, whicu are wuch more sensitive than the metal counters that are being used extensively at present. 3? The Institute of Biophysics, Academy of Sciences USSR should be re? quested to drvelop the best designs of both block (or end) counters and flow counters suitable for biochemical research. 4.. It is recommended that the dotage of tracer atoms used in work with radioactive substances be expressed in international units. 5? The substances being used should be checked for purity. Ttte radio- activity cot?resppnding to the tim~? at which the substance is introduced must be established precisely: 50X1-HUM- .I:,
