Suggestion: Go to a professional national jade quality monitoring center for testing.
The radioactivity of jade is mainly detected by indoor γ -ray spectrum and radiochemical analysis.
In the process of analysis, the tested samples have to be ground and sealed, and the analysis period is about 20 days, so the analysis cost is relatively high.
The Department of Applied Geophysics of China Geo University (Beijing) cooperated with China Jade Industry Association to develop the first jade radioactive detector in China and its related measurement methods and technologies, which passed the expert appraisal of the State Building Materials Bureau and obtained the certificate issued by Beijing Bureau of Quality and Technical Supervision. This instrument is equipped with a probe similar to a flashlight and a small display tester. This portable instrument can be taken to the site for testing without destroying the finished product. It can be tested directly on the finished product, with the test range of 50×50 cm and short test time, which generally takes about 10 minute.
PS: The radiation phenomenon on the earth is earlier than before the birth of human beings, which means that human beings have multiplied in the environment with radiation phenomenon for hundreds of thousands of years. Almost all substances on the earth contain radioactive elements, including ourselves. Jade comes from nature and contains radioactive substances, which is certain and normal.
