The main technical changes in this revision are as follows. 1. Refer to GB/T 4835.1-2012, the name is "radiation protection X, gamma radiation dose equivalent (rate) meter and The monitor was revised to "portable X, gamma radiation surrounding dose equivalent (rate) instrument and monitor". 2. In the verification project, cancel the “overload characteristic” “alarm threshold error” and change the “energy/incident angle response” to “can” Volume response". 3. Refer to the measurement performance requirements and verification methods for the "relative inherent error, repeatability, energy response" project. The technical requirements and test methods of GB/T 4835.1-2012 are modified accordingly. 4. Add “Energy/incident angle response measurement method and calibration factor” in the appendix.
