Ethan Asano is a Ph.D. student in NSSPI who is investigating environmental decontamination in the event of a radiological release. This involves the assessment of ground and surface contamination using experimental gamma-ray detector response validation with Monte Carlo radiation transport simulations. Asano is working with Dr. Shaheen Dewji in the Radiological Engineering, Detection, and Dosimetry (RED2) Laboratory. Radiological releases of concern may include those due to radiological dispersal devices (RDDs), improvised nuclear devices (INDs), or accidents involving the release of fission products.
Additionally, Asano is working on an auxiliary project estimating the external dose persons using ICRP reference phantoms exposed to prompt and delayed radiation using source terms from the RERF Hiroshima and Nagasaki atomic bomb survivor data.
Asano received his Bachelor of Science from the University of Tennessee-Knoxville in Nuclear Engineering with a concentration in Radiological Engineering (2019). He completed two summer internships during his undergraduate career at Oak Ridge National Laboratory. In the summer of 2018, Asano interned with the Center for Radiation Protection Knowledge (CRPK), where he participated in a study of dose and exposure to the skin as a result of fission product release in a Fukushima-Daiichi simulated accident. In the summer of 2019, Asano participated in a study of the air exchange rate impact on radon vapor intrusion in commercial and residential settings as part of the Risk Assessment Information System (RAIS).
