Description

Public Health England (PHE) is seeking to purchase a multifunctional gamma-ray spectrometer and multi-purpose radiation survey meter. The survey meter operating in both contamination and dose rate measuring modes: the instrument must detect alpha, beta, gamma, and X-ray surface contamination and be capable of measuring X-ray and gamma dose rates with energies in the range of 17 keV - 3 MeV. The equipment will be used for the rapid determination of activities of gamma emitters in field surveys or samplings. It needs to be suitable for field survey measurements.
The requirement must meet the following mandatory features.

The multifunctional gamma-ray spectrometer must have/be :
- compact, portable, and digital (~ 4 kg)
- A built-in computer for complex analysis of the measured data
- Wireless communication via Blue-tooth, Wi-Fi
- USB port so data can be exported to other devices
- Real time result stamped by integrated GPS
- Rechargeable power supply (giving at least 10 hours of measurement)
- able to operate in outdoor temperatures ranging between at least -10 to +40 °C and be dust and water resistant
- Monitor and analysis results to be displayed on a large (sun readable) colour graphic display
- an audible speaker and built in microphone for voice recordings, so observations can be recorded and stored with each measurement.
- High sensitivity using a NaI(Tl) scintillator detector (3 '' base diameter and 3 '' height) giving good resolution
- Advanced DSP spectrometer specifications - with 1024 channel, 40 MHz DSP, linear energy corrected pile-up rejector and 200 nS resolution
- Automatic stabilisation on natural background
- Two working modes: survey for terrain scanning and Assay for determining concentrations of pre-calibrated radionuclides.
- Energy calibration of the analyser would be carried out continuously throughout the operating time
- Acquired data is stored in the memory and can be exported to other devices via USB, Wi-Fi or Bluetooth.

The survey meter must have/be:
- Light weight (~0.5 kg), compact, and a rugged 'in one hand' unit
- Water-resistant rubber seals
- A digital LCD numeric display with a backlight facility
- A peak measurement function for determining radiation levels remotely in difficult to access areas
- An audible response
- Displays in µSv/h and cps
- Dose rate range of 0.1 µSv/h to 2 mSv/h. Deadtime correction allowing gamma measurements up to 1999 µSv/h
- Contamination range of 0.1 to 20,000 cps
- Various adjustable alarms (count rate, exposure, dose and counting alarms)
- Designed to work with standard 'off the shelf' standard-size batteries (alkaline and/or rechargeable), providing at least 500 hours of operation (assuming the backlight is off), and provide a low battery indication

If you feel that you can meet the above requirements or would like more information, then please contact Aysel Sarzosa (Aysel.Sarzosa@phe.gov.uk)
