<p><P>PROBLEM TO BE SOLVED: To provide a mobile type personal dosimeter which can set a maximum integrated dose (measuring range) in a given period of time to be large sufficiently, while having high sensitivity, and thus can surely perform expected radiation measurement. <P>SOLUTION: The mobile type personal dosimeter includes a detecting part which detects an ionization current generated by ionization caused by radiation, an integrator which integrates an output current signal from the detecting part and outputs it as a voltage signal and which is equipped with a reset switch, and an arithmetic processing part which sequentially adds up a dosage calculated based on the output voltage signal from the integrator and detects an integrated dose in the given period. Accompanying the operation of the reset switch, the data on the integrated dose from the time of start of measurement or the time of the previous operation of the reset switch are output to a memory and an accumulated exposure dose of a person being a dosimeter holder is recorded, while measurement is performed continuously, with the integrated dose at the time of operation of the reset switch made an initial value. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
