Scintilation Counters Using Organic Compounds [PDF]

Nature, 1949
SEVERAL papers have recently been published1–4 on the efficiency of naphthalene, anthracene and other organic phosphors used in conjunction with photo-multipliers as detectors of ionizing radiations. In view of the conflicting nature of some of these results, we have carried out experiments with these substances, particular attention being paid to ...
