Automation of the monitoring system for surface contamination with [alpha]-active radionuclides

Abstract

The paper presents research on radiation control at nuclear enterprises working with [alpha]-active radionuclides. The focus of the research is on the registration of 239Pu radionuclides on hands surface. The experimental results show the possibility to create a turnstile for automatic monitoring the presence of [alpha]-active radionuclides on hands. Such a device can be used with a minimum helium consumption of 66 liters per hour in a measuring chamber with an open bottom of 5.4 liters.
