About Us

John Caunt Scientific Ltd have been involved with Nuclear Radiation Detection and Measurement since 1975, and we specialise in detectors for all forms of nuclear radiation. We are organised into three main areas:

• Research and development
• The production and disptubution of our own instrumentation
• Representation of other companies, to enhance our range

The production & sale of our own
instrumentation

We manufacture our own instrumentation which includes:

• A mature network system for linking any monitors or detectors back to a central control system
• Neutron measurement instrumentation
• Gamma measurement instrumentation
• Laboratory scalar timer / counting electronics

Radiation Shielding

Neutron Shielding

• Boronated or pure polyethylene sheet for neutrons, which we can cut to size or machine to your drawings
• Castable materials
• Flexible sheets for Neutron or Gammas
• Bespoke machining for our shielding products

Gamma shielding

• Lead shielding products
• Castable materials

With all of these we can offer to do the shielding calculations, and we can also organise the installation with trained and approved engineers.

Radiation Detectors

Our most comprehensive range. We offer a comprehensive range from the following manufacturers:

• Scionix Detectors offer a good range of scintillation materials including, NaI(Tl), CsI(Tl), LaCl3, BGO, BaF2, LiI(Eu), LiGaBO4, and Plastic Scintillators in all shapes and sizes, for all requirements.

• LND offer an affordable & extensive range of gas filled detectors including, GM Tubes, Ionisation Chambers, Proportional Counters and He3 Proportional Counters. Offering very good value.

Representation of other companies

JCS now represent Tracerco in the civil nuclear sector. Tracerco have recently introduced some low cost, high quality, user friendly radiation and contamination monitors based on their unique intrinsically safe range.

Phillips Scientific, Fast NIM electronics - Phillips offer a wide range of modules with either single or multiple inputs.
