Replacement Radioactive Sources-UKHSA Instrument Testing Service (ITS)

UKHSA intends to award a three month contract (plus an option to extend by up to six months) to High Technology Sources Limited for the supply of a suite of replacement radioactive sources required for use in its Instrument Testing Service facilities (ITS). The ITS carries out regulatory performance tests on a variety of radiation monitoring devices, under commercial contracts with the device owners, for which a range of calibrated radioactive contamination and dose-rate sources are necessary. The existing sources have reached the end of their recommended working lives, their radioactive intensity having reduced due to natural decay, and new sources are required such that the radioactive emissions and dose rates required to provide appropriate regulatory instrument testing are maintained thereby enabling ongoing operational capability and efficiency.
