Course description and aims

[Outline]
Fieldwork will be conducted in which multiple types of radiation detectors are used to measure environmental radiation levels on the earth and in the air in Fukushima Prefecture, to give students hands-on experience measuring environmental radiation damage caused by large-scale nuclear accidents. Additionally, samples of fallen leaves and other environmental samples will be collected, isotope identification will be conducted using them, and the spatial distribution of isotope dispersal will be measured. Additionally, students will have their levels of exposure measured with a whole-body counter.
[Aim]
To obtain skills for radiation detection and analysis of radioactivity, and to understand radiation levels after a severe accident of nuclear power plant

Student learning outcomes

To obtain skills for using a wide range of radiation detectors in order to play an active part in nuclear industries

Keywords

Radiation survey meter, Radiation spectrometer, Imaginh plate, Whole-body counter

Competencies that will be developed

Specialist skills Intercultural skills ✔ Communication skills ✔ Critical thinking skills ✔ Practical and/or problem-solving skills

Class flow

After lectures on how to use a wide range of radiation detectors, field work will be performed. Then, retrieved samples will be analyzed.
