IONIZING RADIATION MEASURING DEVICE Russian patent published in 1995 - IPC

FIELD: individual dosimeters. SUBSTANCE: in absence of signal indicating rise of dose rate above threshold level across storage and display circuit output, logical "1" is present across respective input of AND gate. With measuring time setting signal across time interval shaper, signal affording closed state of switch is present across AND gate input. Controlled high-voltage changer is in working condition and its power requirement is proportional to dose rate under measurement. In absence of signal across time interval shaper output and presence of signal indicating rise of dose rate above threshold level, switch at circuit output opens and voltage changer runs in no-load condition with low power requirement. EFFECT: 1.6 times increase in storage battery service life. 1 dwg
