Rad Check Meters (Type : RC705 I&E) manufactured by NUCLEONIX SYSTEMS is primarily designed to measure low level Gamma Contamination (RaC) in various commodities / products which may include food stuffs in solid form, minerals, engineering, steel and casting components etc. It is an ideal choice to measure increased natural background (BG) in houses, factories, buildings etc. in a nuclear disaster scenario. This Portable Meter uses a sensitive scintillator with PMT as the detector. This meter gives an optimum performance in counting Low-Level Gamma Radioactive Contamination (RaC) in a variety of situations.
RC 705B measures contamination in CPS, CPM and Doserate ( µR/h, µSv/h) modes and has built in user presettable alarm facility to declare the product as contaminated. Unit gives audio /visual alarms once it exceeds preset level. It is advised to preset the alarm at least 1.5 times or more than background radiation level, at that place.
