DA-15B Portable Surface Contamination Monitor For Nuclear Medicine Molecular Biology Laboratory
DA-15B Portable Surface Contamination Monitor
Product introduction
DA-15B Portable α, β Surface Contamination monitor is designed for nuclear medicine, molecular biology laboratory, nuclear material transportation and other aspects that have αβ surface contamination and X, γ radiation according to the requirements of ionizing radiation protection. Sensitivity intelligent portable instrument. It has the functions of surface contamination monitor and X, γ dose rate meter. It can be used to measure surface contamination caused by αβ and Xγ radiation dose rate. For α and βγ measurement, the display can be switched, and the measurement is operated by the handle button, and the measurement unit cpscpmBq/cm2 can be converted.
