The dosimeter uses a Geiger-Muller counter tube to measure radiation. When each ray passes go through the GM tube and causes ionization, the GM tube generates a detection current pulse, and each pulse is detected by the electronic tube circuit and recorded as a count. , the displayed value of this dosimeter is the count value in the mode you selected.
Due to the random nature of radioactivity, the count value detected by the dosimeter varies from minute to minute. It is more accurate to take the readings within an average period of time, and the longer the interval is, it is more accurate the average counts.
The detector is used to measure β,γ and X-ray radiation, it is optimal for measuring small changes in radiation levels, and has high sensitivity for most commonly used nuclides.
Safety organizations, such as police and fire brigade, emergency response organizations environmental protection organizations, hazardous materials disposal, metal recycling companies, mines, etc, have a higher chance of being exposed to various radioactive substances.
Ports, wharves, airports, etc, because of the large flow of people and various import and export goods, especially involving entry and exit personnel, the probability of radiation pollution is high.
Hardware factories, ceramic factories, hospitals, research institutions, laboratories, drug administrations, universities, etc., they have a higher chance of being exposed to various low-intensity or leaking radiation.
Private individuals who are concerned about the quality of the living environment and personal safety, such as someone who wants to find the surrounding environmental pollution at home, food, water, etc. (various accidents or terrorist attacks, etc.).
The densely populated place such as meeting room, classroom, exhibition hall, hospitals, department stores, bars, hotel, air port, railway station and entertainment hall, etc. the carbon dioxide detector may be used for ventilation control and environment quality monitoring So, it is used to guarantee body health.
The carbon dioxide may be used for plant photosynthesis. Therefore, it is widely used for agriculture. The air fertilizer with proper concentration may improve output of agricultural crops. When the concentration of carbon dioxide is not sufficient, air fertilizer may be used. It will give great help for whether the vegetable growth or improvement of vegetable.
The air quality concerns healthy growth of animals. If the air is turbid for a long time and the concentration of carbon dioxide is high and ventilation is not provided, the animal will get ill or epidemic disease may burst out. Therefore, installation of carbon dioxide detector at livestock farm may prevent occurrence of animal epidemics.
The carbon dioxide detector is widely used in the Industry such as wastewater treatment, factory building, workshop, temperature, cleaning room, production safety and all types of Industries. Especially, it is very necessary to monitor the carbon dioxide in borehole operation. The carbon dioxide detector is used generally in metal processing, paper pulp and paper making, cleaning and solvent extraction as well as lower temperature cleaning and carbon dioxiderelevant Industry.
