   Nyckelord :Medical physics; Nuclear power plant; Radiation dose; Effective dose; Lifetime attributable risk; LAR; Fallout; Inhalation; Strontium-90; Iodine-131; Cloudshine;

   Sammanfattning : Today, emergency preparedness is needed against both nuclear reactor accidents and nuclear weapons fallout. Both scenarios can lead to exposure of ionizing radiation. Upon exposure, radionuclides will incur a radiation dose both internally and externally. LÄS MER

3. 2. Simulations and Measurements of radiation doses from patients treated with I-131.

   Master-uppsats, Umeå universitet/Radiofysik

   Sammanfattning : The aim of this work is to introduce a couple of new exposure scenariosof interest when personnel, family members and general public are externally irradiated from patients treated with Iodine-131. A series of modied ORNL matematical phantoms were used in Monte-Carlo simulations in PENELOPE-2011 to determine dose rates to: a cab driver where thepatient sits in the back seat at opposite side, a newborn child held by an adult patient, a doctor giving treatment to a patient while leaning over the hospital bed and collective effective dose to bus passengers if the patient travels home by bus.
