NT-P30 channel pedestrian radioactive monitoring system

Product Introduction

The NT-P30 channel type pedestrian radioactive monitoring system is independently developed and produced by Shanghai Minghe Instrument Co., Ltd. It is mainly installed at important entrances and exits such as airports, docks, train stations, banks, immigration security channels, nuclear power plant control areas, nuclear waste treatment plants, and government agencies to monitor whether pedestrians and packages carry radioactive substances. The product has high sensitivity, wide detection range, and short response time, and can achieve advanced functions such as automatic radiation alarm, automatic data storage, automatic capture of on-site photos, and remote data management. When the radioactive level inside pedestrians or packages exceeds the alarm threshold, the system emits an audible and visual alarm signal to prevent the spread of radioactive substances and their pollutants.
