    Abstract : From 1990 to 1998, estimations of the effective dose from external as well as internal irradiation from 137Cs and 134Cs were carried out for inhabitants in rural villages in the Bryansk region, Russia, highly contaminated due to the Chernobyl accident in 1986. The villages were situated about 180 km from the Chernobyl power plant and the deposition of 137Cs was in the range 0. READ MORE

  5. 3. Radioiodine Therapy of Hyperthyroidism - Simplified patient-specific absorbed dose planning

    Author : Helene Jönsson; Malmö Institutionen för kliniska vetenskaper; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; radiobiologi; Radiofarmaceutisk teknik; Radiopharmaceutical technology; absorbed dose. optimise; hyperthyroidism; therapy; 131-I; radioiodine; Nukleärmedicin; radiobiology; Nuclear medicine;

    Abstract : Radioiodine therapy of hyperthyroidism is the most frequently performed radiopharmaceutical therapy. To calculate the activity of 131-I to be administered for giving a certain absorbed dose to the thyroid, the mass of the thyroid and the individual biokinetic data, normally in the form of uptake and biologic half-time, have to be determined.
