BME Project 1: Radiation dose measurements for workers, patients, and chain-of-custody for special nuclear materials

Faculty mentor: Kim Kearfott
Required skills: Motivation to learn, basic programming skills, solid mathematics and physics background.
Dosimeters are passive, integrating materials used to monitor the radiation exposure of workers in nuclear facilities. Although all workers receive dosimeters, there are different types and they have different performance characteristics. New dosimeter types and ways of calibrating and deploying them are being developed in the laboratory. For the first time ever, a method has been developed to extract how dose was delivered as a function of time during the radiation exposure has been developed. Dosimetry systems are also used for medical applications including radiation therapy, diagnostic radiology and nuclear medicine. The limitations of different types of dosimeters are being actively compared and characterized for medical applications, while a novel dosimeter is being developed to serve as a chain-of-custody detector for nuclear treaty verification. Students are engaged in both experiments and data analysis. Topic is especially suitable for students ultimately interested in homeland security/treaty verification, medical physics, nuclear power plant operations, and/or radiation protection.
