Granite is a strong and durable rock that is widely used in construction due to its strength and aesthetic appearance. However, many people are interested in the question of the presence of radiation in granite and the safety of its use in construction. Let's consider this issue in more detail.
The nature of radiation in granite
Radiation in granite occurs as a result of the natural radioactive decay of some minerals that contain radioactive elements such as potassium-40, uranium and thorium. These elements are present in granite in very small quantities, and the radiation they emit is usually so weak that it does not pose a significant threat to health.
Use of granite in construction
Granite is a very popular material in construction, especially for cladding facades, making floors and countertops. The use of granite in construction is considered safe, since the level of radiation in granite is usually below the permissible standards.
Standards of radioactive background for construction
In many countries, there are established norms of radioactive background, which determine the permissible levels of radiation for building materials. Usually, these norms are based on the requirements of the International Commission on Radiological Protection (ICRP) and other international standards. For granite, as a rule, the permissible level of radiation is determined in millisieverts per year (mSv/year) and may vary from country to country.
In the vast majority of cases, the granite used in construction meets the established norms of radioactive background and is considered safe for use. However, in case of doubt or large volumes of work with granite, it is recommended to carry out appropriate radiation measurements to confirm the safety of the material.
