There is an inexplicable panic when it comes to radiation. Many people say that radiation is harmful, so we should first understand what radiation is before we talk about whether it is harmful or not?

What is radiation?

Radiation is a phenomenon in which part of the electromagnetic energy (electromagnetic waves, etc.) emitted from an emitting source.) away from the source of the field and then does not return to the source.digital nitrate tester The energy travels outward in the form of electromagnetic waves or particles (e.g. alpha particles, beta particles). All objects in nature, as long as the temperature is above absolute zero (about -273.15 degrees Celsius), are constantly transferring heat in the form of electromagnetic waves and particles. This transfer of energy is called thermal radiation. In a sense, each of us emits radiation.

Radiation technology itself is a neutral term, but the radiative effects of certain social substances may develop to cause serious harm.radiation detectors The study of radiation can be divided mainly into direct ionization for radiation and non-ionizing radiation. What we ourselves call nuclear weapons, nuclear power plants produce radiation capacity belongs to a kind of ionizing radiation, life cell phones, computers, hairdryers, microwave ovens, WiFi produced by radiation are non-ionizing radiation. Whether you are watching TV, sunbathing, flying, or taking X-rays you can't avoid radiation. However, most of these radiation problems do not pose a single hazard to human health. Let's say, our country is almost every day work to take the subway through the security checker, but the radiation of the security checker is not any harm to the human body, or who would dare to go through the security checker ah!

Ionizing radiation on the human body and protection?

In contact with ionizing radiation in the work, if the protection measures are not appropriate, violation of operating procedures,geiger counter handheld the human body irradiated dose exceeds a certain limit, harmful effects will occur. The degree of reaction of the organism under the action of electric radiation depends on the type of organism, dose, conditions of exposure and sensitivity. Ionizing radiation causes radiation sickness, which is a systemic reaction of the body. Lesions are found in almost all organs and systems, but changes are most pronounced in the nervous system, blood-forming organs and digestive system. Damage caused by ionizing radiation can be classified as acute radiation damage and chronic radiation damage. Acute damage to the body occurs when a certain dose of radiation is received for a short period of time, and this is usually seen in nuclear accidents and radiotherapy patients. However, dispersed exposure to a certain dose over a long period of time can cause chronic radiation damage, such as skin damage, hematopoietic dysfunction, leukopenia and impaired fertility. In addition, excessive radiation can cause cancer and lead to fetal death and malformation.

Sufficient attention should be paid to the safety of radiation. In fact, radiation is not a kind of monster, and the convenience of nuclear technology can be safely enjoyed under appropriate measures. With the development of science and technology, a variety of nuclear technologies continue to penetrate, widely used in industry, agriculture, biology, health care, food safety, environmental protection, resource development and public safety and other fields. The chances of encountering ionizing radiation in our future life will naturally increase.
