Description
Technical Field
The invention belongs to the technical field of protective clothing, and particularly relates to protective clothing capable of preventing ionizing radiation and electromagnetic radiation.
Background
Radiation refers to the phenomenon whereby a portion of the electromagnetic energy emitted by a field source propagates away from the field source and then no longer returns to the field source, with the energy diffusing out in the form of electromagnetic waves or particles (e.g., alpha particles, beta particles, etc.). All objects in nature constantly transfer heat outwards in the form of electromagnetic waves and particles as long as the temperature is above zero (-273.15 c), an energy transfer mode known as radiation. The energy of the radiation is emitted linearly in all directions from the radiation source. The energy given off by the object by radiation is called radiant energy. The radiation is calculated in terms of roentgen/hour (R). Radiation has an important feature in that it is "peer-to-peer". No matter the temperature of the object (gas) is high or low, the object A radiates to the object B, and the object B radiates to the object A. The term is commonly used for ionizing radiation. Radiation is itself a neutral word, but radiation of certain substances may be harmful.
Radiation in a broad sense includes both ionizing and non-ionizing radiation. Ultraviolet rays, visible light, infrared rays, which are non-ionizing radiations, and microwaves, which are closely related to human life, are conventionally called electromagnetic radiation. Thus, radiation as we often speak is generally referred to as ionizing radiation. Ionization refers to the process of releasing one or more electrons from an atom, molecule, or other bound state, which is caused by the collision of a microscopic particle with electrons in the atom with sufficient kinetic energy. With the continuous development of national defense scientific research, radioactive medicine and nuclear technology application, ionizing radiation is widely applied to many fields of modern science and technology, people can not receive the harm of radiation while enjoying the great benefit obtained thereby, and people who often contact radioactive rays can have the symptoms of skin burn, hair loss, eye pain, leukopenia and even myeloma. The traditional material for shielding rays is a lead-containing material, which has been used for more than one hundred years historically, and makes an outstanding contribution to the protection of human health. However, as the development of science is changed day by day, from the viewpoint of modern science, the traditional lead material cannot meet the requirements of social development due to the defects of serious toxicity, high density and the like.
