Radiation Biology Discovery of Ionizing Radiation Health Essay
Humans can be exposed to IR ionizing radiation through spaceflight, a nuclear power plant accident, an atomic bomb, and radiotherapy, and spermatogenesis in the testicles is considered the most radiosensitive. Gy given as a single IR exposure generally causes permanent azoospermia. cell damage caused mainly by IR. Radiation safety is a concern for patients, physicians and staff in many departments, including radiology, interventional cardiology and surgery. The radiation emitted during fluoroscopy procedures is: The biological effectiveness of radiation largely depends on the local energy distribution, the linear energy transfer LET, measured in keV μm. The relative biological effectiveness RBE is defined as the ratio of the physical doses of the densely ionizing radiation, heavy ions, neutrons, compared to the doses of the sparsely ionizing standard. The biological effects of UV radiation depend on the wavelengths involved. The wavelength of the non-ionizing UV spectrum is shorter than that of visible light, but longer than an X-ray, nm, nm. It is classified according to intensity: UV-A 315 - UV-B 280 and UV-C. Kim et al. 2016 2.1. Clinical trials of high-dose local radiation therapy in combination with radiation therapy. Exposure of the heart to ionizing radiation during radiation therapy of intrathoracic tumors and chest wall tumors has long been known to cause radiation-induced heart disease, a usually late and sometimes serious side effect 1-3. While high doses, From ionizing radiation on DNA methylation: from experimental biology to clinical applications, International Journal of Radiation Biology, DOI: 10.1080 09553002.2017.1287454Abstract. Radiation biology is the study of the effects of ionizing radiation on biological tissues and living organisms. It combines radiation physics and biology. The purpose of this chapter is. Ionizing radiation Ionizing radiation Radiation with so much energy that it can knock electrons out of atoms. Ionizing radiation can damage the atoms in living things and thus poses a health risk by damaging tissue and DNA in genes. has enough energy to affect the atoms in living cells, thereby damaging their genetic material DNA.
