Information system on Medical Radiation Applications. Radiation exposure in the Netherlands

Informatiesysteem Medische Stralingstoepassingen 2006. Medische stralingsbelasting in Nederland

Synopsis

In the period 2002 - 2005 the medical radiation exposure in the Netherlands increased by 25 per cent from 0.52 up to 0.65 mSv per caput. Technological development makes it possible to perform more, including more complicated, examinations. Under the authority of the Ministry of Health, Welfare and Sport, RIVM collects and analyses information on medical radiation applications, such as radiological and nuclear medicine examinations. This information is intended to stimulate optimal use of radiation in health care. The mean cause of the increase in radiation exposure is the increase in the examinations, especially important is the increase in the number of CT examinations. Of the above-mentioned 0.65 mSv, 0.27 mSv is due to CT examinations. In the period investigated, the radiation exposure from CT examinations increased by 42 per cent. PET examinations only make a small contribution, but their numbers show a sharp rise. This means that PET examinations make a significantly more important contribution to the radiation exposure caused by nuclear medicine examinations in 2005 than in 2002. In this report, recently collected information used for updating the Information system on Medical Radiation Applications (IMS) website (http://www.rivm.nl/ims in Dutch) is presented and background information on sources supplied. For more information see the IMS website: http://www.rivm.nl/ims (in Dutch).
