Rad Check Meter (Internal Detector / External Detector Probe)

Rad Check Meter (Internal Detector / External Detector Probe) RC705I / RC705E

Technical Data
manual 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).

Detector Scintillator coupled to a Photo multiplier Tube.
Options A. Built in detector scintillator size 1” x 1” B. External detector with scintillator size 1” x 1”.
Acquisition Mode CPS: (0-50000) or CPM : (0-5000)
Measurement Range Dose rate: (1-10000) µR/hr or (1-99999) nSv/hr

Better than +/-25% with Cs-137 (upto 100µR/hr)
Over range This instrument will show over range above the 10000 µR/hr
Alarms Facility Provision for audio/visual alarms if it exceeds preset level.
Alarm Preset Level User selectable in all modes.
Sensitivity a. 0.1 µR/hr/1nsv/h in terms of Radiation unit.
b. Interms of minimum measurable RaC, it Can detect 30 KBq of Co60 contamination homogeneously distributed in a Steel sample upto 10 cm away with internal probe arrangement and upto 20 cm with external probe arrangement.
