In order to investigate the effect of paints available in the market on the radon exhalation rate from buildingmaterials, several bricks were collected. These bricks were plastered with a mixture of cement and sand. Beforemeasurements bricks were dried for 24 hours. These plastered bricks were then coated with white wash and again dried for 1-2 hours. After drying the bricks were coated with different brands and colors of paints. Radon exhalation ratesmeasurements were carried out for these painted bricks through sealed can technique II using LR-115 type II detectors.Radon activity varies from 845.71 Bq m-3to 1682.86 Bq m-3.. Radon exhalation rate varies from 506.17 mBq m-2h-1 to1007.22 mBq m-2h-1 whereas the effective dose equivalent for radon decay products vary from 59.69 µSv y-1 to 118.77 µSvy-1.Radon exhalation is found to increase slightly with golden (yellow), Asian (orange) and Berger (yellow) while itdecreases with others.
