Abstract
After the TEPCO’s Fukushima NPP Accident in 2011, it became necessary to evaluate the absorbed dose distant from beta emitting nuclides. We focused our attention on the beta sources (such as 90Sr/90Y) released in the accident. We try to perform benchmark analysis using PHITS code for the evaluation of the absorbed dose from beta radiation. The simulated absorbed dose rates for beta radiation by PHITS agreed with the measured absorbed dose rates to within 6% in the range from 1 to 1000 μm deep in ICRU tissue. The PHITS code showed almost the same results as EGS5 code. The PHITS’s ability to visualize with T-Deposit is useful and powerful to provide presentation Dose MAP from beta radiation.
