METHOD AND DEVICE FOR DETERMINING A PERSON'S DOSE IN MIXED NEUTRON/PHOTON FIELDS

摘要

A method for determining a person''s dose, of the environment - equivalent dose, of the effective dose and of the kerma in mixed neutron - / photons - fields, characterized by the,a) that only a semiconductor detector both for the determination of the neutrons - as well as of the photons dose is used,b) that the pulse heights information from the semiconductor detector for the determination of neutrons - and photons dose is used, the pulses in a suitable pulse height interval are summed up and are divided by an average response and thereby simultaneously both the neutrons - as well as the photons dose is determined,c) that the semiconductor detector with a sensitive surface between 0,1 cm² and 30 cm² at the voltage applied between 1 v and 100 v a sensitive depleted layer with a thickness of between 1 μm and 400 μm, as well as a dead layer with a thickness of between 10 nm and 20 μm in front of the sensitive layer,d) that extends in front of the semiconductor detector, an air gap (up to 2 cm wide) is located,e) that..
