Statement of Work For Alpha Analyst

Title: Alpha Analyst Document Date: 30 May 2019

1. Scope The Radioanalytical laboratory requires the use of alpha spectroscopy for the preparation of its bioassay and environmental samples (alpha emitting nuclides that can't be measured by any other means). The radioanalytical laboratory currently owns one alpha spec system. The current system will only hold 24 samples and the lab requires additional counting capability that will integrate seamlessly to the existing system.

1.1 Background: The Radioanalytical Laboratory needs additional capacity for added alpha spectroscopy workload. The new Instrument will enable the laboratory to double its alpha spectroscopy throughput (Bioassay and environmental samples). It will also constitute a usable backup instrument in case of a failure of the 24 chamber unit already in operation. The purchase of this equipment will directly support analytical capability for nuclear events requiring fast radionuclide analysis for mitigation of health, social and economic effects. The alpha spectroscopy system will help with recoil contamination protection. Even with the most carefully prepared samples system operators cannot eliminate the possibility of contamination of the detector with recoil nuclei. This unwanted contamination leads to decreased measurement sensitivity and ultimately longer counting times until some detectors are eventually rendered useless.
