Contract Award for Replacement of Three Aging Radon Active Monitors

Tender description

PHE had a requirement to replace three of their aging active radon monitors. The requirement is for its Centre for radiation, chemical and environmental hazards (CRCE) lab in Chilton. PHE has awarded the work to Southern Scientific as they are the sole UK distributors of the AlphaGUARD system. This system was identified as the only solution able to fulfil PHE requirements. The solution had to provide the following: - One single portable solution (due to its use in both a laboratory and field environment) - Able to operate in passive (diffusion) and active (pumped air) mode - Capable of measuring over a range of time intervals, ideally 1 minute to 1 hour - Able to store at least six months of data recorded at one hour intervals - Capable of mains and battery operation - Capable of a minimum of one week's operation in diffusion mode on battery power - Capable of downloading data to a PC for analysis. Downloaded data should be available to use as a text file or other format suitable for use with Microsoft Excel. - Able to measure a range of radon concentrations from 50000 Bqm-3 PHE currently has other radon monitoring equipment located at this site (radon in soil, radon in gas) which is manufactured by Saphymo. Therefore in order for continuity of work there was a requirement that the solution purchased by PHE be compatible with current equipment. PHE published an early engagement notice (EEN) explaining our intention to direct award and invited other suppliers to contact if they believed they could offer an alternative product. PHE received no contact in relation to this.
