Radon monitor

Abstract

The invention discloses a radon monitor, comprising a collecting part, a detecting part and a computation processing part. The collecting part comprises a detecting room; the detecting part comprises a silicon detector and an amplifier; the silicon detector is arranged on the inner wall of the detecting room; the computation processing part comprises a data input interface, a data processor, a memory, a display and a keyboard, wherein the data input interface is connected with the detecting part, the data processor is connected with the data input interface; and the memory, the display and the keyboard are connected with the data processor; the silicon detector detects the content of radon and radon daughter in air which enters the detecting room and transmits a detecting signal to the amplifier; and the amplifier transmits the detecting signal to the computation processing part. The invention adopts the silicon detector and sets a high-pressure collecting electrode so as to improve the collecting efficiency of the radon and the detection sensitivity and accuracy of apparatus. The radon monitor has simple structure and low cost, is easy for operation and convenient for carrying, and can be widely used for continuously and automatically detecting the radon of various residential buildings.

Description

technical field [0001] The invention relates to a detection instrument for radioactive elements, more specifically an instrument for monitoring radon. Background technique [0002] With the improvement of people's quality of life, people's homes are constantly being updated, and decoration has become a necessary process before people live in new houses. However, many newly purchased decorative materials will be used in the decoration process. These materials contain radioactive substances harmful to the human body. More than 55%, it is a great threat to human health, and the incubation period of its onset is mostly more than 15 years. According to the National Safety Council of the United States, the number of deaths due to radon in the United States is as high as 30,000 every year! my country also has serious radon pollution. Since 1994, my country has surveyed 1524 office buildings and residences in 14 cities. The radon content per cubic meter exceeds the national standa...

Problems solved by technology

[0003] 1. The track etching method is a passive method, which has the disadvantages of long time and high cost (taking up the time of testing equipment and increasing the rental cost of equipment)

[0004] 2. The activated carbon box method is also a passive method. Although the cost is relatively low, it lacks automatic control and will increase labor costs.
