[15p-423-1] Radiation Education Activities to convey the image of Quantum Physics
Keywords:radiation, University-high school collaboration, active learning
This paper describes our activity to convey "interest in the quantum mechanical world" through the radiation measurement to the high school students. Collaboration between high school and university has been promoted called as “Super Science High School program (SSH)”. The high school students are interested in science through the SSH program. However, there is a gap between the high school education and modern science. Gap keeps students away from science.
The author has the program by connecting the lecture and experiment. High school teachers want the high school-college collaboration as the style of active learning. So we lectured the radiation physics to the high school students at first, and experimented. The high school students understood well by comparing the lecture and the experimental results.
In the lecture, the author explained that the natural radioactive materials produce three types of ionizing radiation: alpha radiation, beta radiation and gamma radiation. The author also taught the Fukushima Dai-ichi nuclear accident. It was also taught that the reason why Fukushima recovery efforts are difficult from the viewpoint of radiation protection.
The author explained that nuclear decay is a phenomenon that follows the law of probability in the radiation measurement. Next, the students experimented on radiation shielding and absorption curves of beta rays with radiation sources. A simple cloud chamber was also used to visualize the trajectory of alpha radiation and beta radiation.
From radiation measurement experiments, students were interested in probabilistic phenomena. Even though the experimental results were not uniquely determined, it told students the interest of science. The author concluded that the students were interested in the wonders of phenomena due to radiation.
