With the increasing development of human beings in the field of nuclear energy, nuclear technology has become increasingly widely used in people's daily applications, such as industrial measurement, exploration, testing, medical treatment, material production, and food processing. Therefore, the source of radioactive materials in the environment has become more complicated, and the amount of radioactive materials discharged by humans into the environment is also increasing rapidly, and the harm to human health has attracted more and more public attention. The physical detection of environmental radioactive samples is the monitoring and counting of the total α and β of various environmental media samples. The measurement technology of environmental sample collection, sample preparation, measurement methods and data composition has been formed, and an efficient and highly sensitive total α has been established. , Β monitoring count.
1. Product introduction
The low-background α and β measuring instrument has independent design of multi-channel detection systems such as one, two, four, six, and eight channels, which can measure multiple samples at the same time, and respectively give the total α and total β activity concentrations in the sample; Alpha sample or beta sample can also be measured separately. It has the characteristics of sensitivity, low background, simple structure, convenient, stable and reliable operation. The instrument can complete the measurement of water samples, biological samples, environmental samples, aerosol samples and other samples through different sample preparation methods and computer software parameter settings.
