What Does a Radiographer Do?

When the radioactive ray decays, the penetrating particle beam emitted from the atomic nucleus is divided into A-ray, B-ray, and C-ray, among which the C-ray has the strongest penetration force. In addition, radiation is harmful to the environment and the human body. The same radioactive element emits several different rays because of the multi-layered distribution of the material around the nucleus. The outermost material is the least constrained by the atomic nucleus and the easiest to escape, but its own speed and energy are also the smallest, its penetrating power is also the smallest, its wavelength is large, and its frequency is low. The material in the middle layer is closer to the nucleus, and it needs higher speed and energy to escape from the nucleus of the nucleus. Therefore, it will have higher speed and energy during radiation, stronger penetration, smaller wavelength and higher frequency. The innermost layer of matter is closest to the nucleus and rotates around the nucleus at the fastest speed. When escaping from the nucleus, it has a high speed and energy, has a strong penetrating power, a short wavelength, and a high frequency.

In addition to accelerators,

There are generally two ways to directly use the reactor as a ray source:

(1) In the horizontal direction or vertical direction of the reactor's center (active area), open some ray-extracting channels, and use the rays in the reactor directly at the holes. Lead out like this

There are also two ways to indirectly use a reactor as a ray source:

(1) Use of neutrons and some of the reactor

People are familiar and unfamiliar with the dangers of radiation. In ordinary people's impression, it is related to the explosion of the extremely powerful atomic bomb and hydrogen bomb. With the peaceful use of the world

What is a radioisotope and how does it cause harm? Occupy the same place in the periodic table,

use

The industry uses the ability of radiation to penetrate matter, used to detect and control the thickness of steel plates or paper, and check for trachoma and cracks in metal. In agriculture, the seeds are irradiated with radiation to mutate the seeds, cultivate excellent varieties, and increase agricultural yield. In medical health ^[1] , the use of radiation can be used to check and treat malignant tumors.
