“…(1) Debugging of radon detector: before the experiment, disconnect the connector between the catheter and the cover of the sample box, adjust the radon meter to the purge mode, introduce the dry and clean air into the measuring chamber of the radon meter, and discharge the radon and water vapor [15,20]. When cycle is set to 5 and recycle is set to 9, it means that the time for the radon detector to sample and measure radon concentration is 5 minutes and the sampling time is 9 [21].…”

The thickness and compaction degree of the overburden soil on the beach of the uranium tailings reservoir has an important influence on the radon reduction rate. A theoretical model of radon exhalation is established and an experimental device is designed. The main results are as follows. (1) The radon reduction rate increases with the increase of thickness. When the soil compaction degree is 85.5%, 90.2%, and 94.8%, the radon reduction efficiency increases significantly when the thickness increases from 5 cm to 10 cm, and when the soil thickness is over 10 cm, the increase of radon reduction efficiency tends to be stable. When the compaction degree is 80.9%, the radon reduction rate always increases obviously with the increase of the thickness of the overburden soil, but the increase rate shows a downward trend. (2) The radon reduction rate increases gradually with the increase of compaction degree, and the increasing trend becomes less obvious when the compaction degree is more than 85.5%. Besides, the effect of the change of soil compaction on radon reduction rate decreases with the increase of soil thickness. The calculation formulas about the effect of thickness and compaction degree on radon reduction rate can guide the design and construction of radiation protection of uranium tailings reservoir.

“…Such defects, as a rule, create deep energy levels in the band gap of silicon. The study of the impact of radiation on various physical properties of silicon is important from the point of view of studying the term of operation and changes of the performance of devices and measuring equipment manufactured on its basis, used in atomic reactors, accelerators of nuclear particles, aerospace industry, space, scientific research [6][7][8][9][10]. In particular, there is a significant demand for the radiation resistant pressure sensors for such areas of science and technology, whose manufacture in economically developed countries is about 60% among all other sensors of physical quantities.…”

The tensoresistance at the uniaxial pressure along the crystallographic direction [100] for n-Si single crystals, which were irradiated by the different doses of gamma quants was investigated. On the basis of the theory of anisotropic scattering and experimental data of the tensoresistance the dependences of the parameter of mobility anisotropy on the uniaxial pressure for the data of single crystals are obtained. It has been shown that for unirradiated n-Si single crystals, the parameter of mobility anisotropy does not depend on uniaxial pressure since the alloying impurities of phosphorus will be completely ionized at T=77 K. For the gamma - irradiated n-Si single crystals the parameter of mobility anisotropy will decrease with an increase in exposure dose by reducing the screening effect. In this case, it is necessary to take into account the mechanisms of electron scattering on the impurity ions, impurity complexes, which consist of several ions of the impurity and on the fluctuation potential, which leads to the appearance of gradients of resistivity. The changing of relative contribution of these the scattering mechanismsat at the uniaxial pressure determines the obtained dependences of the parameter of mobility anisotropy and the tensoelectric properties of gamma-irradiated n-Si single crystals.
