Alanine ESR Dosimetry System

The United States Department of Agriculture (USDA), Animal Plant Health Inspection Service (APHIS) is conducting market research to determine if there are domestic sources capable of providing a Spectrometer and Dosimeter Reader meeting the agency's needs. The ESR5000D alanine ESR dosimetry system is the only system that can meet the agency's needs, and it is widely used in phytosanitary irradiation. The system must have unique and specific features that provide the regulatory-required research-grade sensitivity and reliability in a format that requires minimal infrastructure. • The system must meet the specifications of the alanine dosimeter used by APHIS and the commercial phytosanitary irradiation facilities. • The ESR5000 is the exclusive model utilized by the National Institute of Standards and Technology (NIST), APHIS, and APHIS-approved phytosanitary irradiation facilities. • The system enables the program to perform traceability calibration and dose cross-checks among NIST, APHIS, and commercial facilities using the same system error and type of alanine dosimeters.
