چکیده انگلیسی
A new radon chamber has been designed, constructed, and tested. The design was chosen to meet the needs of several different radon detection techniques, both active and passive. The chamber is a cubic shape made of pixy glass with volume about 0.65m3. On top, it has a circular opening with double lock system for entering and removing samples without significant disturbance of the inside concentration. It also has the possibility to expose passive radon detectors at different levels inside the chamber. In addition, two fans, with variable speeds, were fitted in two opposite corners to maintain the uniformity of radon gas inside the volume. This calibration chamber can be used to perform researches and studies on radon behavior, in addition to calibrating different types of detectors (passive and active) which are used for measuring radon and its daughters. Solid radium-226 source with activity of 122Â kBq was placed at the bottom of the chamber to generate radon.
