According to the safety behavior of nuclear district heating reactor, the calculation method of accidental release of radioactivity is derived.

However, unlike the simple exponential that describes radioactivity, which has only one variable, a stretched exponential describes a process controlled by several independent factors.

The transportation and transformation of 14 C phenanthrene in a closed 'plant lava nutrient solution air' chamber system was studied by using radioactivity technology.

The first is the internal heat produced by radioactivity inside the earth. The second is the external heat supplied to the earth by the sun.

Article 49 materials containing radioactivity in excess of standards or materials containing toxic and harmful substance easy to dissolve in the water may not be used in a Marine construction project.

In 1896, Henri Becquerel had inadvertently discovered radioactivity when he left some uranium ore in a drawer on top of an undeveloped photographic plate, on which the uranium left a "shadow."
