Question: What is radioactivity?1.Info: Radioactivity is a natural process in which atoms spontaneously separate and transform into smaller atoms. During separation, they emit radioactive radiation. Radiation is everywhere and in everything. From the floor to the products you use. You cannot detect radiation with your senses. This is not a problem because in most cases radiation is not bad for your health. Your body is also a small source of radiation. Some substances radiate more than others.

During separation, they emit radioactive radiation.2.Info: Radioactivity is the emission of radiation by atoms. Each atom has positively charged protons and neutral neutrons and is surrounded by negatively charged electrons. Usually the particles are in equilibrium. But sometimes the balance of the atom is disrupted because electrons escape. The atom corrects this by emitting alpha, beta or gamma radiation. Because the composition of the atom changes, a new atom is created. If this atom is unstable again, it continues like this. Until a stable atom remains, which can take a long time. Atoms that exhibit this phenomenon are called radioactive. Radioactive radiation is therefore an incorrect formulation because it is not the radiation that is radioactive but the atom that disintegrates. Examples of radioactive substances used daily are iodine, cesium, strontium, plutonium and uranium. Mostly...... middle of paper......assuming iodine is used, iodine will go there too. Radioactive radiation is often used to sterilize used surgical instruments. Radioactive substances are also used in research into chemical reactions in cells. In industry, radioactivity is used, among other things, to: • detect defects in metal constructions • measure the thickness of paper • detect leaks in pipes and (underground) welds • sterilization. foodstuffsPreviously, radioactive substances were used in fire alarms. However, these are no longer permitted. Useful information: Source: Information on radioactivity and its consequences. applications. (nd).
