Radon is an invisible, odorless, and chemically inactive radioactive gas produced by the decay of uranium ore. Various types of equipment and components have been proposed for use in effective radon detection. In this paper, we used a radon counter with a PIN photodiode radon-sensor module. Using electrostatic collection and the PIN photodiode, a high sensitivity radon detector for air has been developed. The calibration system has also been developed using a linear regression analysis technique.

The linear regression is a linear approach for modeling the relationship between a scalar dependent variable y and one or more explanatory variables denoted X. A linear regression analysis method is used to improve the performance of the instruments using light scattering method. The data measured by these instruments have to be converted to actual PM10 concentrations using some factors. These findings propose that the instruments using light scattering method can be used to measure and control the PM10 concentrations of the underground subway stations. In this study, the reliability of the instrument for PM measurement using light scattering method was improved with the help of a linear regression analysis technique to continuously measure the PM10 concentrations in the subway stations. In addition, the linear regression analysis technique was also applied to calibrate a radon counter with the help of an expensive radon measuring apparatus.
