The Spanish radon program: achievements and future

One could say that the Spanish Radon Program began in 1988 with the development of a nationalsurvey on indoor radon in Spanish houses. Today, 10 years later, many activitites by differentinstitutions and Universities have been carried out and a good information about the radon problemhas been achieved. Spain consists of 50 provinces which are amalgamated to form 17 autonomousregions. In this paper, we show the results of a major research and development program which is stillin progress. The Spanish Safety Nuclear Council has been promoting, coordinating and supporting thetasks carried out by the different laboratories involved in the Radon Program. Among the largerprojects, the following are noted:- National survey on indoor and outdoor gamma radiation and radon concentration in houses.- National survey on natural radioactivity in soils and building materials.- Development of protocols for measurements of natural radionuclides as well as physical parametersthat have influence on the indoor radon levels such as radon emanation factor, exhalation rate anddiffussion coefficient.- Study of radon entry models and mitigation techniques.- Radon measurements in workplaces, including health spas and caves.A brief description of the results achieved for the above goals set up by the Radon Program is shownin this paper which also include the main objetives for the future Spanish Radon Program.
