The standard describes the requirements and the procedures for testing such dosimeters against these requirements. The requirements apply to direct reading dosimeters designed to measure ionizing electromagnetic radiation (X-rays or gamma-rays) with energies from approximately 20 keV to 3 MeV. Procedures are given for the testing of any accessory electrometers or chargers that are used to operate, or read-out, these dosimeters. The purpose of this standard is to specify the procedures to be used for the inspection, test, construction, and performance evaluation of direct reading dosimeters of the electrostatic/electroscope type. New IEEE Standard - Active. Inspection, test, construction and performance requirements for direct reading electrostatic/electroscope type dosimeters designed to measure the personal dose equivalent or ambient exposure delivered by external sources of ionizing radiation (X-rays or gamma rays) are given. .
