What´s Radioactivity and What can it be used for?

Radioactivity has a very dangerous meaning. In many cases, it is so. But, it is also very convenient. Radioactivity has been used in both good and bad aspects. It is still one of the most fascinating phenomena of human discovery and regeneration: division of atoms. My question is what is radioactivity and what it can be used for. In 1896, a French man named Henry Becquerel unexpectedly discovered radioactivity. He combined the crystals of uranium with a paper plate covered with paper.

Phosphate rock radioactivity is 23 uranium which was first observed in 1908 when British physicist R. Strutt discovered that the radioactivity of the phosphate rock sample was many times higher than the average rock of the crust , Their decay products are in equilibrium with each parent element in the ore. ; 228 Th, 224 Ra, 220 Rn, 212 Pb, 212 Bi. Among all the radionuclides in the phosphate rock, 226 Ra is of particular interest due to its long half life, radiation toxicity and its relative physical and biological mobility. The nuclide is more important as a parent nuclide of gaseous 222 Rn, which together with the solid decay product constitutes an important source of radiation exposure. According to reports, the concentration of 226 Ra in these wastes is close to 1 Bq / g 25, 27.

Activities to manufacture or use radioactive materials generate radioactive waste. Various processes in medicine, scientific achievements and all other fields create dual products including radioactive waste. Radioactive waste may take the form of gas, liquid, or solid and its radioactivity level varies. Waste may remain radioactive for hours, months, or hundreds or even thousands of years. It is dangerous and it is very difficult to find a suitable radioactive waste disposal facility because it can keep radiative for a long time. Depending on the type of waste to be disposed of, the disposal facility may take longer to contain the radiation. Proper disposal is essential to ensure public health and safety, and the quality of air, soil, and water.
