All governments are responsible for protecting their populations against health hazards and business fraud in the food sector. Considering the expansion of international food trade in Cuba and the necessary protection of consumers, animals, plants and the environment in general, in our country a sanitary control system for food has been designed, taking into account the regulations in force in this matter, both national and international. The Environmental Radiological Surveillance Laboratory (LVRA) of the Radiation Protection and Hygiene Center (CPHR) has been in charge, since 2000, of the radiological surveillance of foods that are marketed in the national territory. This Surveillance Program is executed within the framework of the National Pollutants in Food and Water Surveillance Program, directed by the National Directorate of Environmental Health (DNSA) of the Ministry of Public Health (MINSAP). The tests carried out by the LVRA aim to verify compliance with the permissible levels for radionuclides in food in force in Cuba, as one of the elements that contributes to guaranteeing the food safety of both imported and nationally produced products. The work presents and analyzes the results that have been obtained in these years of radiological surveillance. [ABSTRACT FROM AUTHOR]

The use of hot spring waters from deep geologic layers in spas has been identified as typical scenarios of exposure to natural radiation. These scenarios can affect the patients under treatment, as well as the workers of these facilities. Therefore, characterization studies are being undertaken in these spas in order to evaluate the radiological impact they produce on these categories of population. The Elguea Spa, located on the northern coast of Villa Clara, Cuba, is equipped to provide services by using hot spring waters and mud existing in the zone of the spa. Its waters contain significant levels of radon. Present paper shows the dose estimates made from the radiological characterization of the spa and its surroundings, both for workers and the patients receiving treatment. The dose values are in the range of 1,01 to 180 μSv/year for workers, the most irradiated group, and these results suggest that there is no need for special protection measures or regulations.
