Even a small dose of radiation increases the risk of cancer. X-ray examinations, radiation treatments and the use of radioactive isotopes should be considered so that the use of radiation should be more advantages than disadvantages.
The research and monitoring of the use of radiation in health care is aimed at ensuring that radiation doses for patients as well as staff are kept to a minimum. X-ray examinations of patients seek the smallest possible amount of radiation for diagnostic X-ray pictures of the best possible care and results. This goal is possible to achieve by improving the X-ray equipment, giving them the quality requirements and the training of users of radiation as well as by making regularly control visit to hospitals.
