In order to determine the exact radioactive level of rough jadeites with the purpose of clearing people's minds of doubt concerning radioactivity of gems and jades, the authors analyzed the specific radioactivities of natural radionuclides such as ²²⁶Ra, ²³²Th and ⁴⁰K in ten samples from three different types of rough jadeite using low background multichannel gamma spectrometer (HPGe). The results show that the specific radioactivities of radionuclides concerned are lower or only a slightly higher than the minimum detectable limits, and both internal exposure index (I_Ra) and external exposure index (I_γ) of the samples are by far below relevant national provision of radionuclides in building materials. These data indicate that the radioactive level of rough jadeites is rather low and corresponds to natural radioactive background, and hence there is no harm of radioactivity.
