FJ-310A (GM) Protection Level X, Gamma Radiation Measuring Instrument
FJ-310 protection level X and γ radiation measuring instrument is mainly used for accurate and rapid measurement of X, γ and β radiation. The instrument is convenient to carry and easy to operate. The instrument adopts dual GM counter tube, which automatically switches the measurement of high and low range, and can alarm normally even when the staff encounters a large dose. This instrument can be used for environmental protection departments to detect environmental background conditions, radiation detection near medical ray equipment, non-destructive testing (i.e., X-ray detection) equipment whether there is radiation leakage, nuclear power plant near the residential environment background measurement. The instrument implementation standard is HJ 1157-2021 "Technical Specification for Measurement of Environmental Gamma Radiation Dose Rate".
