We have developed an air monitor which is possible to measure rapidly and sensitively the concentration of plutonium for the environmental monitoring at an accident of a nuclear reprocessing plant. The monitor is designed to collect airborne plutonium by drawing the ambient air through a filter and to detect the activity by alpha spectroscopy. The following two methods are equipped with the monitor: continuous measurement at atomospheric pressure and batch measurement at vacuum. The description of the air monitor and the results of performance test are reported.

Professor Clake proposed a darstic change of radiation protection system of 1990 ICRP recommendation in 1999. The change is expected to affect current radiation protection system. The background of the propsal and the changes are introduced. Opposition, questions and requests to the new proposal are introduced.
