Chi tiết:
РМ1405 Survey Meter measures beta radiation flux density from contaminated surfaces and ambient dose equivalent rate of gamma and X-ray radiation.
Survey Meter is designed for the wide range of radiation safety applications and may be successfully used by radiation control services personnel, first responders, employees of security service and customs, as well as personnel whose work includes solving problems of local gamma and beta radiation sources detection or single objects contaminated by gamma and/or beta radiation sources.
