In reality, objects are all radioactive, including soil, water, atmosphere, and humans themselves. Sesame ash roadside stones are taken from nature and contain a certain amount of radioactivity, which is normal. Radioactivity refers to the radioactive substances produced by the decay of radioactive elements such as radium, thorium, uranium, etc. contained in objects, mainly radon.

Sesame ash roadside stones have low levels of radioactivity and do not generate uncertainty. Even if the sesame ash roadside stones exceed the standard, the radiation is absorbed at a low and trace level, which will not cause infertility or lead to the occurrence of nasal and throat cancer. When the radiation level remains above 15msv for three consecutive years, it can cause harm to humans. An increase in quantity can trigger cancer, with a probability of one in a million, which can be ignored. The data shows that the radiation value of sesame ash curbstone is much lower than this number, only 0.5msv, which can be ignored.
