Abstract:

The cross-linking effect of radiation on acrylic paint was investigated in order to block the emission of radon from walls and to reduce its harmful influence on the human body. As a result, a new method is proposed for the development of an anti-radon coating. The investigated coating was irradiated with gamma-rays, and the absorbed dose was in the range of 1 to 10 kGy in increments of 1 kGy. Subsequently, the cross-linking effect of the different absorbed doses on the coating was examined. The results indicated that when the absorbed dose was less than 2 kGy, the cross-linking effect of the coating increased with the absorbed dose, and the corresponding radon prevention efficiency also gradually increased. An absorbed dose of 2 kGy resulted in a maximum value of 67.3% for the flood prevention efficiency. In the case when the absorbed dose was more than 2 kGy, the cross-linking effect gradually decreased with an increase in the absorbed dose, and the anti-radon effect of the paint progressively deteriorated.
