Notes:
Abstract Methods of monitoring low plutonium concentration in the inner and outer atmosphere are analyzed and compared. It is shown that monitors based on the gross alpha counting of air filters are not sensitive enough to measure reliably plutonium activities below 1 MPC. A spectrometric discontinuously operating monitor using a gridded ionization chamber and a membrane filter having 70 cm2 active area is described. Plutonium activities of the order of 0.01 MPC /1 mBq.m−3/ can be measured by the spectrometer at 1 h sampling and 1 h counting time.
