Radiation Leak In Russia 's Khabarovsk What We Know So Far

Who fact sheet on ionizing radiation, health effects and protective measures

Includes key facts, definition, sources, type of exposure, health effects, nuclear emergencies, who response. Ionizing radiation can remove electrons from the atoms, i.e In terms of natural radiation sources, there are more than 60 different naturally occurring radioactive materials present in the environment, with. We work to strengthen radiation protection of the public, patients and workers worldwide Radiation exposure ionizing radiation exposure is measured as absorbed dose in gray (gy) The effective dose measured in sievert (sv) takes account of the amount of ionizing radiation energy absorbed, the type of radiation and the susceptibility of various organs and tissues to radiation damage.

Radiation is the emission of energy as electromagnetic waves or moving subatomic particles Natural radiation comes from many naturally occurring radioactive materials found in soil, water, air and in the body Every day, people inhale and ingest forms of radiation from air, food and water. All skin types can be affected Natural uv radiation levels depend on sun elevation, latitude and altitude, cloud cover and ground. À mesure que les usages des rayonnements ionisants se multiplient, les dangers qu’ils peuvent comporter pour la santé, s’ils ne sont pas correctement utilisés ou confinés, augmentent.

Ionizing radiation is radiation with enough energy that to remove tightly bound electrons from the orbit of an atom, causing that atom to become charged or ionized

Here we are concerned with only one type of radiation, ionizing radiation, which occurs in two forms There are several forms of electromagnetic radiation, which differ only in frequency and wavelength يمكن أن يفاقم التعرض المفرط لجرعات الإشعاع خطر الإصابة بأنواع معينة من السرطان في الأمد الطويل. فقد يتسرب أثناء الطوارئ النووية اليود المشع الذي يؤدي استنشاقه أو ابتلاعه إلى تركزه في الغدة الدرقية وتفاقم خطر الإصابة.
