<p>PROBLEM TO BE SOLVED: To simplify the circuit constitution for an amplifier part and to reduce the electric power consumption, in a radiation measuring device such as a personal dosemeter. SOLUTION: Sensors S1, S2 are connected to be reversed to each other in polarities of detection signals, and a preamplifier 10 and an amplifier 12 are used in common by the two sensors S1, S2. Pulse-height discriminators 14, 16 for extracting components of the respective polarities are provided in a following stage of the amplifier 12.</p> |
