Abstract—In the present study, the alpha radioactivity from radon emanated from some ceramic samples collected from different countries was measured using the can technique, containing CR-39. The average 222Rn and 226Ra concentrations are found to be 371.79 Bq m-3 and 1.68 Bq kg-1, respectively. The highest radon exhalation rate was found in Chinese ceramic. The values of effective radium content are less than the permissible value of 370 Bq kg-1.
