What is the difference between “radioactivity and radioactivity”, benefits and harms to human beings?

Radioactivity and radioactivity are different These two words are similar. But when translated into Thai, it has different meanings as follows:

Radioactive A radioactive element, also called radioactive element, is an unstable nucleus. able to emit radiation and transform itself into another element There is a danger to the human body and living things to the genetic level. The emitted radiation is invisible to the naked eye. must be detected with an inspection tool

The period of decay and radiation of radioactive elements is called “half-life” e.g. cesium-137 It has a half-life of 30 years. It takes 150 years to have 3% of its energy remaining.

Examples of radioactive elements currently in use are radium-226, uranium-238, etc.

radioactivity (Radioactivity) is an adjective. Refers to the instantaneous decay of three types of radiation: alpha, gamma and beta radiation.

The radiation emitted by radioactive elements is called There are three types of radioactivity:

Alpha rays is a positively charged particle. It consists of two neutron particles with low penetrating ability. Can pass through the air only 2-3 cm. Caused by the decay of some radioactive substances such as uranium and thorium.

Beta rays is the electromagnetic waves generated by the atoms excite the outermost electron to escape and the next electron takes its place Excess energy is released in the form of X-rays.

Gamma rays is an electromagnetic wave It is a radiation with high penetrating power. Caused by unstable nuclear fission. Usually occurs in conjunction with alpha and beta particles. Good protection against gamma rays is lead, thick concrete, etc.

Industrial Uses of Radioactive Elements used with power plant and the medical industry such as

• Benefits of Radioactive Elements in the Electrical Industry

Some types of radioactivity can be used as fuel to generate electricity. In foreign countries, there is nuclear power plant technology. which can provide high electrical power But in exchange for making a good defense system and people in the community have knowledge and understanding

• Benefits of radioactive elements in the medical industry

Some radioactive elements are used to treat cancer patients. The treatment method is called radiation. which has building safety requirements And there is training for staff to use. Hospitals that use radiation equipment must implement a careful safety system.

• Benefits of radioactive elements in the gem and jewelry industry

Radioactive elements help change some gems to have beautiful colors, reduce flaws and increase the value of jewelry to be more beautiful.

Some radioactive substances are used to kill bacteria in food. help in preserving food It is beneficial to keep food for a longer time.
