Description

We have developed an advanced method for enhancement of the sensitivity of dosimeters, in which a modified algorithm of the coherent demodulation technique is introduced. A test gamma-dosimeter was produced, which consists of five pairs of CsI scintillator-photodiodes and four Pb plates, and many experiments were performed using 60Co gamma sources. The background component was reduced to about 1/133, and then, gamma rays of 0.06 mR/h = 1.55 x 10-8 C/(kgh) could be detected against a background of 2.66 mR/h = 6.86 x 10-7 C/(kgh). (author)
