متن کاملEstimation of the collective effective dose to the population from medical x-ray examinations in Finland
The collective effective dose to the population from all x-ray examinations in Finland in 2005 was estimated. The numbers of x-ray examinations were collected by a questionnaire to the health care units (response rate 100 %). The effective doses in plain radiography were calculated using a Monte Carlo based program (PCXMC), as average values for selected health care units. For computed tomograp...
