The radiation effects on environment and human health
The first chapter of this diploma thesis emphasizes in the understanding of the radiation key aspects; the definition of radiation, the characteristic measurement sizes, the radiation sources and mainly the radiation categorization on ionizing and non-ionizing.
Ionizing radiation is responsible for many important human health effects, as well as environmental effects. Therefore, the best part of this thesis addresses the health effects due to the exposure of humans to the radiation emitted by radioactive materials, during the occurrence of the radioactivity phenomenon. Nuclear accidents, atomic bombs, unintentional storage of radioactive wastes, exposure to radioactivity from medical devices can cause a range of effects from skin damage to cancer or even genetic mutations. However, ionizing radiation has also many positive effects to humans; x-rays, Computed Tomography, radiotherapy and various other medical uses of radiation show its worth to protection and improvement of human health.
One of the main radiation forms is the solar radiation. The best part of the solar radiation spectrum is included in non-ionic radiation. The beneficial effects of solar radiation both on human body and the environment are well known since antiquity (improvement of the cardiovascular system, confront of skin and respiratory diseases, photosynthesis, etc.). Though, the acute solar exposure, as well as the long-term exposure can cause adverse effects on health. Solar radiation commonly affects the eyes, the immune system and especially skin, where can be caused multi-level cancers.
The last part of this thesis addresses another part of non-ionic spectrum: radio waves, as well as low-power electrics and magnetic fields. This type of radiation does not directly affect the human health. However, "basic restrictions" and "reference levels" have been established internationally to avoid any harmful effect from long-term exposure to these types of radiation.
