Technical Data

Most Widely used product by Metal Industry in India

Rad Check Meter Type RC 705 ( I & E) manufactured by NUCLEONIX SYSTEMS is primarily designed to measure Radioactive Contamination (RaC) in metals such as steel, brass, Aluminium, castings, other alloys and machined parts. It is an ideal choice for all export houses who are into the above line of products. This Portable Meter uses a sensitive scintillator with PMT as the detector. This meter gives optimum performance and measures very efficiently Low-Level Gamma Radiative Contamination (RaC) in a variety of situations.

RC705 I & E measures contamination in doserate in Siverts / hr (nano/micro), Roentzen / hr (micro),  CPS, CPM. It 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.

Unit can detect less than 0.05µSv/hr in a field of 0.2 µSv/hr during a period of 1 sec (when tested with Cs-137 and Co-60).

Features


  • Ideal choice for checking Radioactive Contamination (RaC) in metal Industries including Steel, Brass, Aluminium, Foundry and engineering industrial products.
  • It is an ideal choice to measure increased natural background (BG) in houses, factories, buildings etc. in a nuclear disaster scenario.
  • Manufactured conforming to & ANSI N42.17A performance specifications for Health Physics instrumentation (portable)
  • Has Four modes of measure- ment CPS,CPM ÁR/hr and nSv/hr.
  • User settable alarm facility.
  • Highly sensitive compared to other similar meters.
  • Probability of detection the alarm condition is more than 99%.
  • System designed to withstand Humidity, Shock / Vibration, Temperature (upto 55°C).
  • Designed to comply EMI/EMC.
