Abstract
The transportation of radioactive material is often dedicated at delivering medical radionuclides from production facilities to hospitals and clinics. HotSpot simulations are conducted to assess the radiological impact of hypothetical road transport accidents followed by fires, involving alternatively 18F, 99Mo, 123I, or 201Tl, each at International Atomic Energy Agency transport regulation A2 activity level. The impact of burning fuel quantity, wind speed, atmospheric stability, and nuclide solubility is analysed. The findings indicate that the total effective dose (TED) increases if the burning fuel quantity decreases; the wind speed increases; the atmospheric stability decreases. Radionuclide solubility may have contrasting effects on TED, depending on the chemical element. Under the most unfavorable conditions, the calculated TED (in Sv) is equal to 6.52 × 10-7 (18F), 7.34 × 10-8 (99Mo), 2.36 × 10-6 (123I), and 6.27 × 10-6 (201Tl). Finally, the TED is calculated for several diagnostic nuclides applying the worst-case scenario.
期刊介绍：
Radiation Protection Dosimetry covers all aspects of personal and environmental dosimetry and monitoring, for both ionising and non-ionising radiations. This includes biological aspects, physical concepts, biophysical dosimetry, external and internal personal dosimetry and monitoring, environmental and workplace monitoring, accident dosimetry, and dosimetry related to the protection of patients. Particular emphasis is placed on papers covering the fundamentals of dosimetry; units, radiation quantities and conversion factors. Papers covering archaeological dating are included only if the fundamental measurement method or technique, such as thermoluminescence, has direct application to personal dosimetry measurements. Papers covering the dosimetric aspects of radon or other naturally occurring radioactive materials and low level radiation are included. Animal experiments and ecological sample measurements are not included unless there is a significant relevant content reason.
