For a large number of building materials that may be used in the home decoration process, experts suggest that the radioactivity level of the building materials itself should be strictly controlled. For example, granite should be used with caution in the interior, and when building materials into the field, it is best to have a qualified department or agency to conduct radioactivity level testing.
◠During the decoration process, it is best not to use a decorative material in a large area of ​​the room. It is best to conduct a radioactive background test before the renovation of the new home, which will help the selection of stone and whole body bricks.
â— When purchasing stone and building ceramic products, you should ask the dealer for the radioactivity test report. Pay attention to whether the report is the original one. The name of the business in the report and the name of the purchased product are consistent.
In addition, there are test result categories (A, B, C). According to national regulations, Class A radioactivity is relatively small, and its scope of use is not limited; Class B is not easy to be used for interior decoration, and other places can be used; Class C can only be used for exterior decoration of buildings.
For stone and tile products that do not have a test report, the best way is to ask the expert to use the instrument for testing before deciding whether to buy it.
If the room has been renovated, experts can be invited to the site for testing. If the radioactivity index is too high, measures must be taken immediately to replace it. If the standard is not high, you do not need to remove it, keep the room ventilated frequently or take effective air purification measures.
â— If the radioactivity level of the home improvement is detected, first look for building materials with relatively high radioactivity levels, such as tiles, toilets, sinks, granite, etc., and then replace them after confirmation. At the same time, it is necessary to ventilate frequently to reduce the residence time in a high radiation level environment and properly maintain the distance from the radiation source.
â— If the radiation level of an object is too high and cannot be replaced immediately, consider adding a suitable and thick enough shielding material around it to "block" or "weak" the radiation of the radiation particles.
