A study of the irradiation temperature coefficient for L-alanine and DL-alanine dosemeters.

abstract：:The current revision of the Swiss Radiological Protection Ordinance aims to bring Swiss legislation in line with new international standards. In future, the control of radon exposure in dwellings will be based on a reference level of 300 Bq m(-3). Since this value is exceeded in >10 % of the buildings so far investiga...
