Description

<p>We developed an educational program to estimate attenuation properties for natural radionuclides from commercially available reagents. Potassium chloride, rubidium chloride and lutetium oxide were purchased and used as radiation sources for 40K, 87Rb and 176Lu, respectively. These nuclides have long half-lives and exhibit a variety of radioactive decays. The radiation counts decreased exponentially with the increased thickness of aluminum shields, and each radionuclide showed a specific half-value layer. In addition, the radionuclides in Doll stone were identified by the X-ray spectrometry. In conclusion, commercially available reagents are available for planning educational programs for radiation and radioactivity.</p>
