How much do you know about X-ray radiation?

X-rays are a type of electromagnetic wave that has always existed in our living environment. Visible light, infrared, ultraviolet, X-ray, and gamma rays are mixed together in the atmosphere, including signals received by mobile phones, signals from various frequency bands and bands, and transmitted signals. We cannot distinguish or feel it with the naked eye, so we are constantly exposed to various radiation in the air.

There are two dosage units for radiation. The first is the absorbed dose, which is a physical quantity that describes the degree of biological damage caused by radiation to the human body. It is expressed in international standard units in grams. The second is dose equivalent, which is a physical quantity that uniformly represents the degree of harm of various radiation to the human body. The international standard unit is the millivolt. In fact, 1 Gory and 1 HiV are numerically equivalent, and there is basically an equal relationship.

There are two sources of radiation that people are exposed to in their daily lives: natural radiation and artificial radiation. Natural radiation refers to radiation in the living environment, which exists in soil, rock layers, water, and atmosphere. Human survival cannot do without radiation. The second one is artificial radiation, which is X-ray equipment used in various industries and medical fields. The natural background of radiation varies in different environments. If it is closer to the sun and has a higher altitude, its radiation is higher. There are relatively few areas with lower elevations.

Part of the radiation is beneficial, often referred to as "going out and sunbathing", but in fact, it can kill bacteria and improve immunity. The harmful side of it is that if its dosage is very high, direct irradiation may cause radiation sickness in the human body and may lead to cancer.

A portion of the radiation comes from daily life, whether it is from flying, eating fruits and vegetables, living in brick and mortar buildings, including near nuclear power plants, or radiation from the universe, all of which are natural sources of radiation.

Artificial radiation can cause a certain degree of harm, but as long as protective measures are in place, the radiation dose that operators are exposed to is close to the natural local area, and even lower than the dose required to take X-rays at the hospital. Therefore, before using industrial X-ray equipment, ensure that lead protection is in place, and there will be no radiation threat.
