GB-Warrington: UKRI-2291 Radiation Monitors for Gamma Detection Outside Concrete Test Facility Shielding

Descriptions

NOTE: This notice was updated on 22 July 2022 for the following reason: The deadline for UKRI-2291 Radiation Monitors for Gamma Detection Outside Concrete Test Facility Shielding, has been extended. The new deadline for suppliers to submit their Expressions of Interest is 14:00hrs on 08th August 2022.(This tender requires the design, manufacture, quality control testing and calibration of an initial eight (8), fixed ionising radiation monitors and applicable control software with the option of purchasing an additional four (4) in the subsequent three years. The intended use for these monitors is in fixed occupied locations outside the primary shielding. In these locations, radiation is heavily attenuated by the accelerator components and shielding structures. The shielding has been designed such that dose rates external to the shield walls of the accelerator should be below 1 µSv/h, however, unexpected beam losses can occur which could lead to unplanned, elevated dose rates above the design criteria outside the enclosure. The purpose of these monitors is to detect dose rates at systematically selected locations around the accelerator and either warn those in the vicinity or terminate power to the accelerator depending on the magnitude of the detected dose rate.)
