High-voltage source for G-M counter uses 10-kc blocking oscillator and Cockcroft-Walton multiplier, to give 550 v stabilized by zener region of D1. Range for pulsed operation is 0.5 to 50 milliroentgen per hour. For current mode, same 18503 G-M tube is used, and current in range of 50 milliroentgen to 5 roentgen per hour is logarithmic function of radiation intensity.-R. W. Lehnert and J. M. McKenzie, Radiation Survey Meter, Electronics, 35:8, p 50.
