This report summarizes the contents of the session of the Health Physics and Environment Science Division, which was held in Atomic Energy Society of Japan 2019 Spring Meeting. In this session, six students and young researchers who engaged in the field of nuclear energy and radiation gave a lecture about health physics and environmental science research through their expertise. After the all presentations end, we took discussion time about the issues and future development in this field with all attendees. In this report, we summarized each lecture outline and discussion contents.

For the reduction of the external dose of workers in the process of Fukushima Daiichi Nuclear Power Station (1F) decommissioning and to propose an effective decontamination plan, it is necessary to grasp the distribution of locally existing hotspots. A one-dimensional radiation distribution measurement system applying time-of-flight method to scintillating optical fiber has been widely applied after the 1F accident, but in a high dose rate environment such as 1F reactor building, a pile-up of signal and chance-coincidence effect of a sensor is a problem. Therefore, as an integral-type measurement method that can avoid problems such as pile-up, we propose a reverse-estimation method which measures the wavelength spectrum at the fiber edge and estimates the incident position of radiation to the fiber using the fact that the attenuation length of light depends on the wavelength.
