This thesis presents the findings of a study undertaken to determine the radioactivity present in building materials in the Republic of Ireland. A total of 70 samples of commonly used building materials was collected from various manufacturers and suppliers throughout the country and analysed using a HPGe gamma ray spectrometer. The specific activities of 226Ra 232Th and 40K were measured in all samples and results ranged from minimum values o f 2.6, <1, and 8.0 Bq kg-1 to maximum values of 193, 73, and 2255 Bq kg-1 for 226Ra, 232Th, and 40K respectively. 137Cs activity was also detected in some samples. Results obtained were compared with relevant national, E.U. and international legislation and guidance, and with the results of similar studies undertaken in other countries. These activities would suggest that the use of such building materials in the construction of domestic dwellings or workplaces in Ireland is unlikely to give rise to any significant radiation exposure to the occupants. In general, these activities were comparable to the results of sim ilar studies undertaken in other countries.
