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 60 Co gamma sources. The background component was reduced to about 1 133 , and then, gamma rays of 0.06 mR/h = 1.55 × 10 −8 C/(kgh) could be detected against a background of 2.66 mR/h = 6.86 × 10 −7 C/(kgh).
