PPT-Risk Managing Acute Ionising Radiation

Exposure Dr David J Heslop Radiation Hazards Nonionising Electromagnetic spectrum Ionising Alpha Beta Gamma Neutron Xradiation Routes of Exposure Direct exposure line of sight Secondary exposure. What about ionising radiation sources that are not work- related? We are all exposed to natural background radiation from sources outside of work, such as: the earth itself; cosmic radiation from Uranium 238 (U238) Radioactive DecayHere we are concerned mainly with ionising radiation from the atomic nucleus. It occurs in two forms, rays and particles, at the high frequency end of the energy Io Learning Objectives. I must be able to recall when ionising radiation is emitted. . I should be able to describe the three types of ionising radiation.. I might be able to explain the dangers of ionising radiation.. Ionising radiation Radiation is all around us all day, every day. It sustains our lives. We see because our eyes detectradiation, whether from the sun or from a glowingfire, keeps us warm.
