Most of these sources are not useful for constructing a dirty bomb. They are used to diagnose and treat illnesses, sterilize equipment, inspect welding seams, and irradiate food to kill harmful microbes. These sources are found in hospitals, on construction sites and at food irradiation plants. It is far more likely that radioactive materials used in a dirty bomb would come from low-level radioactive sources. However, increased security at these facilities would make theft of these materials extremely difficult. The highest-grade radioactive materials are present in nuclear power plants and nuclear weapons sites. There has been a lot of speculation about where terrorists could get radioactive material to use in a dirty bomb. What are sources of radioactive material? Certain radioactive materials dispersed in the air could contaminate several city blocks, create fear and require costly cleanup. However, at the levels created by most sources, there would not be enough radiation in a dirty bomb to cause severe illness from exposure to radiation. Gauging how much radiation might be present is difficult when the source of the radiation is unknown. The primary danger from a dirty bomb containing a low-level radioactive source would be the blast itself. The level of contamination will depend on how much radioactive material was in the bomb, as well as the weather conditions at the time of the blast. Because the material will disperse as a result of the explosion, areas near the blast will be contaminated. A dirty bomb is a conventional explosive device that has been adapted to spread radioactive material and contaminate only a small area. The atomic explosions that occurred in Hiroshima and Nagasaki were caused by nuclear weapons. What is the difference between a dirty bomb and the atomic bombs used in Hiroshima and Nagasaki? The main purpose of a dirty bomb is to frighten people and contaminate buildings or land. A dirty bomb is intended to disperse radioactive material into a small, localized area around an explosion. All Health Care Professionals & Patient SafetyĪ dirty bomb, or radiological dispersion device, is a bomb that combines conventional explosives, such as dynamite, with radioactive materials in the solid, liquid or gaseous form.Clinical Guidelines, Standards & Quality of Care.Health & Safety in the Home, Workplace & Outdoors.Birth, Death, Marriage & Divorce Records.
