After the revision of the law, certain amounts of uncontained radio isotopes (RI) became available for student practice at junior high and/or high schools. In this study, we developed several teaching materials and teaching methods using RI for student practices, e.g., determination of genetic substance, verification of the central dogma theory, verification of rules of base composition in DNA, relationship between atomic number of shielding materials and transparency of gamma ray, relationship between distance from RI and effective dosage, determination of radioactivity of cesium in soil. We evaluated performance of inexpensive radiation detectors for the usage in these schools.

修订法律后，在初中和/或高中可供学生实践一定数量的无线电同位素（RI）。 In this study, we developed several teaching materials and teaching methods using RI for student practices, e.g., determination of genetic substance, verification of the central dogma theory, verification of rules of base composition in DNA, relationship between atomic number of shielding materials and transparency of gamma ray, relationship between distance from RI and effective dosage, determination of radioactivity of cesium in soil.我们评估了这些学校使用的廉价辐射探测器的性能。
