Natural radioactivity in stones is a phenomenon caused by trace amounts of radioactive elements like uranium, thorium, and potassium-40. While most garden stones emit minimal radiation, certain types—such as granite or shale—may have higher levels. Prolonged exposure to these materials can pose health risks, including increased cancer likelihood, especially if they contaminate soil or water.

To ensure garden safety, test suspicious rocks with a Geiger counter or consult local geological surveys. Avoid using highly radioactive stones in landscaping, and opt for safer alternatives like limestone or sandstone. If contamination is suspected, replace affected soil and limit direct contact. By understanding and managing stone radioactivity, gardeners can create a healthier outdoor space.

Regular monitoring and informed material choices help mitigate risks, allowing you to enjoy your garden without unnecessary exposure to natural radiation.
