METHOD FOR COUNTING TRACKS OF ALPHA-PARTICLES IN NITROCELLULOSE DETECTOR Russian patent published in 1997 - IPC

Abstract RU 2082183 C1

FIELD: physical instruments. SUBSTANCE: method involves exposition of detector, chemical etching and spark counting. Data of spark counting are calculated using degradation factor which is calculated using equation Kf=εch+(εo-εch)[1-(1-f)D]/f/Σch+(εo-εch)(1-f)d, where εo is efficiency of recording of alpha-particles, εch is characteristic efficiency, D is number of detector exposition days, d is number of days from exposition end till processing, f is degradation factor, in particular, ratio between number of tracks to their initial number. EFFECT: increased precision. 2 dwg, 1 tbl
