3 days ago · It has a half-life of about 6 hours, which is long enough to conduct medical tests but short enough to minimize radiation exposure. For example, in a cardiac stress test, technetium-99m helps create images of blood flow in the heart. Environmental Monitoring: Scientists monitor the decay of cesium-137 to track nuclear contamination. Cesium-137 ...
1 day ago · This calculator is designed to estimate the cosmic radiation exposure you might experience during a flight. The concern about exposure to radiation during flights has become increasingly relevant with the rise in air travel and the heightened awareness of radiation's health implications.
2 days ago · Thus, it is important to develop approaches to immediately detect and respond to such radioactive contamination, as well as to effectively manage and monitor radioactive wastes, to better protect humans and ecosystems from elevated risks of radiation exposure.
4 days ago · The interactions of the α $\alpha$-particles with the medium in the simulations were handled through the G4EmStandardPhysics_option3 package, used for proton and ion therapy. 35, 36 This Geant4 package uses the stopping powers from the International Commission on Radiation Units and Measurements (ICRU) 49 report for energies < $<$ 8 MeV. 37 ...
4 days ago · Radiation effects on embryonic and fetal development are generally considered low risk compared to the normal risks of pregnancy. Most diagnostic x-ray and nuclear medicine examinations are <50 mSv and have not been demonstrated to produce any significant impact on fetal growth and development.
