Poly radiotherapy
WebIn this work, the effect of seven different sample orientations from 0° to 90° on pilot and non-pilot ignition of PMMA (poly(methyl methacrylate)) exposed to radiation has been studied with experimental and numerical methods. Some new and significant conclusions are drawn from the study, including a U-shape curve of ignition time and critical mass flux as sample … WebThese could lead to radiation sickness, cancer, genetic mutations, or even death. However, the levels of natural radiation on Earth are generally low and pose little risk to humans. Dosimeters are useful to medical personnel treating a person exposed to acute radiation as they can measure the amount of radiation a person has been exposed to ...
