We developed a method to collect natural radioactive nuclides in the air by a simple method. Dust contained in the air in the storage room was sucked with a vacuum cleaner and collected on a cotton paper used as a filter. The radioactive nuclides, 214Pb and 214Bi from 222Rn were collected on the filter. The radiation dose had enough quantity to analysis using a GM counter for education. The PC was connected to the GM counter and displayed the change of the radiation dose in real time. The PC calculated the apparent half-life of the radioactive nuclides, and the half-life was approximately 40 minutes. We applied this measurement to the radiation education teaching material for junior high school students. This teaching material promoted that a student understood "radioactive decay of the atom", "half-life" and "the measurement of the radiation". |
