Nuclear radiation is usually recognized as a variety of radiations, present in all matter and a universal phenomenon. Nuclear radiation is a stream of microscopic particles emitted by nuclei during the transition from one structure or energy state to another. These streams of particles contain four main types of radiation: α particles, β particles, γ & x rays, and neutrons. Α particles are the nucleus of the helium atom, consisting of two positive protons and two neutral neutrons; β particles are the high-energy streams of positronic or negatronic electrons; γ rays and X-rays are high-energy electromagnetic waves. Neutrons are part of the nucleus of an atom and are part of the chemical elements.

Nuclear radiation ionizes or excites matter, so it is called ionizing radiation. Ionizing radiation is divided into direct ionizing radiation and indirect ionizing radiation. Direct ionizing radiation includes charged particles such as protons. Indirect ionizing radiation includes photons,tds meter neutrons and other uncharged particles. Ionizing radiation is harmful to the human body: for example, it impairs the functioning of tissues and organs and can have serious effects and cause cancer, so the management of nuclear radiation requires special care and attention.

Nuclear radiation is relatively easy to detect because of its penetrating and ionizing properties. A wide range of nuclear radiation detectors are also available in the market for rapid measurement of radioactive substances in different states and environments.

In brief, conventional nuclear radiation detection mainly detects four types of rays, namely alpha, beta, gamma and neutron, and the equipment and instruments routinely involved are mainly as follows.

1. Personal dose alarms & X, γ radiation and personal different dose alarms

Personal dose alarms and X, γ radiation personal dose alarms are mainly used in hospital X-ray rooms, nuclear power plant staff and other radiation exposure monitoring of X-ray and γ-ray exposure in the work environment, such equipment can monitor the environment in real time, X-rays, γ-rays can set the alarm threshold, when the alarm threshold is reached, the alarm will be issued in a timely manner, to remind the staff to pay attention to safety.

Of course, in addition to real-time personal dose alarm, there is also a device called pyroelectric radiation monitor. The role of this equipment is also to monitor the exposure of X-rays and γ-rays in the working environment of radiation workers,dosimeter vs geiger counter but not real-time monitoring and display of monitoring values. Instead, it utilizes a pyroluminescent emitter as a dosage element that accumulates the energy of the received rays. The dose element is heated by the pyroluminescent heating device and emits light, which is converted into an electrical signal output for display through a photomultiplier tube. Therefore, it is not possible to provide real-time warning, and can only monitor the total amount of radiation received by the wearer over a period of time. Thermoluminescent dosage tablets, on the other hand, can be used on a large scale due to their low price.

Therefore, in many cases, the two personal dose alarms used in conjunction, can be very good protection of personal radiation safety.

2. α, β-ray surface contamination meter

α, β surface environmental pollution meter can be used mainly through a variety of objects attached to the surface of the α, β pollutant data to analyze and measure (such as dust, etc.), its main management function is to detect the level of contamination below the regulation limit value level, timely detection is a detection surface whether there is contamination, to determine the enterprise contamination point location and scope, and give the amount of contaminated nuclides in the contaminated area. Measurement, the detector to do our best possible close to the surface of China to move, once the detection of pollution, the detector should be in the region to develop positioning methods of measurement to get enough time to confirm the level of pollution control. The instrument can be widely used in social and environmental education departments, higher vocational colleges and universities, nuclear physics laboratories,geiger counter radiation detector scientific research institutions, radioactive laboratories, nuclear power plants, radioactive measurement stations and for other radioactive places of personnel hands, clothing and students use the test bench, test teaching equipment α, β surface treatment pollution measurement, in order to be able to decontaminate in time, so as to achieve the protection of their own work to serve the safety of personnel.
