The RMS30:

"A flexible & intuitive radiation detection system"

The System

Designed to be flexible and intuitive, the JCS RMS30 operates a growing range of custom designed gamma & neutron probes and is the go-to solution for a broadening range of applications across our nuclear sector.

Flexibility underpins the operation of the RMS30 where sample time, counting period, alarm thresholds (per probe) can be defined by the operator.

The RMS30 can be portable (battery-powered) or mains-powered, bench or wall-mounted, have variable cable lengths for probes and even a remote alarm module to accommodate a multitude of measurement scenarios.


  • Dual channel input
  • Accepts a variety of JCS designed smart probes
  • Recognises probe-type
  • Supplies correct voltage to all system probes
  • Network Capabilities
  • User-defined units: sV/h, CPS, rem/h
  • Displays data (e.g. μSv/h) from 1 or 2 probes
  • Logs data to internal memory for PC retrieval by USB
  • Portable

Further Info >


The RMS30 accepts a growing number of JCS designed probes and accessories, which will further extend how and where the instrument can be deployed.

The RMS30 is currently being used for:

  • Decommissioning
  • POCO
  • Area gamma monitoring
  • Area neutron monitoring
  • In cell radiometric profiling
  • Remote monitoring
  • Obsolescence management
  • Facility monitoring
  • Underwater monitoring

Case Study

Live animal monitoring in the Chernobyl exclusion zone

An innovative portable detector for the live-monitoring of radionuclides in small terrestrial animals in the Chernobyl exclusion zone.

Radionuclide measurements in wildlife are required to demonstrate that the environment is not significantly impacted by radioactivity. Determination of internal radionuclide activity concentrations often requires destructive sampling. Development of alternative (non-lethal) measurement methods is therefore desirable.

Next Exhibition

SRP Annual Conference 2020

We will be showcasing our range of instruments, shielding, detectors and exhibiting our RMS30 gamma and neutron sensors which, as a smart device, is gaining some serious traction across the UK nuclear landscape.

This year we’ll also be demonstrating the BrightSpec MCA range, their new dedicated SiPM MCA and their bGamma, gamma spectroscopy software.

When: 28 – 30 Apr 2020
