摘要

A room of 31 m~3 in volume was selected and walls were classified as W, N, S, E, C, and F for west, north, south, east, ceiling, and flooring, respectively. Eighteen dosimeters were installed at a constant distance of 74 cm from the west wall, 533 cm from the east wall, 105 cm from the ceiling, and 191 cm from the flooring of the room. All the windows and doors were closed for 90 days to observe explicitly the variations of~(220)Rn and its progeny levels with respect to the distance from walls, ceiling, and flooring. In addition, the dosimeters were also deployed in upper and lower parabolic fashion to see the variations. Higher concentrations were observed at the wall, ceiling, and flooring of the room but they were reduced as the detector was moved away from them. However, Rn progeny concentration did not show appreciable variation with the distance.
