title: A pilot study of natural radiation in Danish houses.
abstract: A pilot study was carried out to establish techniques and procedures for the measurement of indoor radiation in Denmark. A passive cup dosemeter was designed containing CR39 track detectors and TLD's to measure radon and external radiation, respectively. A total of 82 dwellings were selected covering most regions of the country. The dwellings were monitored in two three-month periods, one in winter and the other in summer. The average dose rate in air from external radiation was 0.09 muGy h-1. In the winter the average radon concentrations were 88 Bq m-3 and 24 Bq m-3 for single-family houses and flats, respectively; and in the summer the corresponding values were 52 Bq m-3 and 19 Bq m-3.
