Stochastic risk estimate for barium radiological examinations in Malaga (Spain)

The aim of this research work has been the estimation of the stochastic ris k for five barium examinations. The sample was the population attending the Radiological Service of the 'Nuestra Senora de la Victoria' University Hos pital, who had been treated with some barium examinations, set in five diff erent groups: oesophagus tract, oesophagus-gastric-duodenal tract, intestin al tract, enteroclysis and double enema. To estimate the stochastic risk, it is necessary to know the organ dose. Th is can be calculated from the dose-area product which allows us to determin e the effective dose using software. The dose-ru ea product is the most sui table quantity to measure in these types of examination. We have evaluated the contribution that each procedure provides to the gene tically significant dose, somatically significant dose, collective effectiv e dose, annual effective dose 'per capita' and detriment, which are useful for assessing the population risk of cancer or hereditary effects after x-r ay exposure. The contribution to the genetically significant dose is 6.7 mu Gy, to the s omatically significant dose 8.82 mSv-yr, 16.07 person-Sv for the collective effective dose, 0.03 mSv for the 'per capita' annual effective dose and th e annual aggregated detriment is 0.33.
