Sources of Ionizing Radiation There are many sources of naturally occurring radioactive material, such as Uranium and Thorium in soil and rock, and Carbon-14 in the atmosphere. IAEA Radiation Oncology Physics: A Handbook for Teachers and Students - 16.1 Slide 2 16.1 INTRODUCTION Risks associated with radiation exposure can only be restricted but cannot be eliminated entirely because: • Radioactive substances producing ionizing radiation occur naturally and are permanent features of the environment. Radiation from the sun sustains life on earth and determines climate. Orphan radioactive sources or other radioactive material are sometimes unintentionally collected as scrap metal destined for recycling. 2019 . Radiation also comes from substances that are all around us every day. Incoherent Light SourcesIncoherent Light Sources Thanh Tran Sun's surface, Images courtesy of SOHO consortium.

Radiation can be described as being one of two basic types: non ionizing and ionizing. For example, false teeth result in a radiation dose to the mouth. Higher the frequency or lower the wave­length of a radiation, […] ll1e designation … Presentations. Radiation Sources Health Physics Society - Power Reactor Section Radiation Science Education Introduction Scientists have studied radiation for over 100 years and we know a great deal about it. At ground level the muons, with energies mostly between 1 and 20 GeV, contribute about 75 % of the absorbed dose rate in free air.The remainder comes from electrons produced by the muons or present in the electromagnetic cascade. Some of the radiation sources listed result in an exposure to only part of the body. Students work through Plan: Starter: Post it notes stuck to a 1-10 scale as per instructions on slide 1.

It was used to provide continuous source of IR radiation for use in spectroscopy A cylindrical rod or tube composed of a mixture of certain oxides such as zirconium oxide (ZrO 2), yttrium oxide (Y 2 O 3) and erbium oxide (Er 2 O 3) at a ratio of 90:7:3 by weight. Exposure to ionizing radiation arises from naturally occurring sources (such as radiation from outer space and radon gas emanating from rocks in the Earth) and • Man-made radiation sources are now widespread. These recommendations were essentially adopted as a resolution of the Forty-second General Conference of the IAEA in September 19981. Sources of InformationWe can’t truly perform controlled experiments so we look atpopulations that were accidentally or otherwise exposed.Radiation exposed populations include: Early X-ray workers Radium Dial Painters Hiroshima and Nagasaki Survivors Uranium Mine Workers Ankalosing Spondilitis Ringworm Accidents Natural background radiation.
