1Multi-Modal Radioactive Shipping Radioactive Material Production, Transportation, Use, and Possible MisuseMulti-Modal Radioactive Shipping
2Radioactive Material Production, Transportation, and Use Radioactive Material Production, Transportation, Use, and Possible MisuseRadioactive Material Production, Transportation, and UseThe creation, shipping, and use of radioactive material is highly regulated (IAEA, NRC, DOT, etc.).High activity sources can only be produced by sophisticated methods (e.g. reactors & accelerators).High activity sources can only be obtained after special licensing to ensure their safe use and their security.Similar regulations exist in other countries were radioactive material is produced or used.
3Shielding Requirements Limit Portability Radioactive Material Production, Transportation, Use, and Possible MisuseShielding Requirements Limit PortabilityFor sources: the higher the activity, the more shielding you require to transport the source.Density sources:typically 1.5 Ci to 2 Ci.120 LbsNeutron sources:4 to 19 Ci130 to 200 LbsLarge Densometer:55 mCi68 to 275 Lbs
4Portable Radiography Sources Radioactive Material Production, Transportation, Use, and Possible MisusePortable Radiography Sources“Top strength” industrial radiography sources can burn fingers and cause radiation sickness within a few minutes.Effects drop off dramatically with distance. Outside of 3 meters, acute effects rare even after hours of exposure.Sources are constructed to meet rigorous testing standards. A typical source is encapsulated in two (2) TIG welded Stainless Steel Capsules.Source material itself is often metal (Cobalt or Iridium) or embedded on non-soluble ceramics or “microspheres” to prevent inhalation of radioactive material if the source encapsulation is breached.
5High Activity Source Transportation Radioactive Material Production, Transportation, Use, and Possible MisuseHigh Activity Source TransportationContainers that ship high activity sources are meant to withstand very punishing accident conditions.
6Conclusion: Radioactive Material Production, Transportation, and Use Radioactive Material Production, Transportation, Use, and Possible MisuseConclusion: Radioactive Material Production, Transportation, and UseHigh activity radioactive material is highly regulated.Industrial sources are very robust and made not to leak.When dangerous quantities are shipped, the material is put in a container capable of withstanding harsh accident conditions.Very high activity industrial/medical sources are facility based and difficult to remove.
7How Might High Activity Radioactive Material be Misused? Radioactive Material Production, Transportation, Use, and Possible MisuseHow Might High Activity Radioactive Material be Misused?Expose people to an external source of radiation.Disperse radioactive material using conventional means.Explosively Disperse radioactive material [a “Dirty Bomb”].Create a Nuclear Weapon (this requires special nuclear material)
8Potential consequences of dispersal of radioactive material into... Radioactive Material Production, Transportation, Use, and Possible MisusePotential consequences of dispersal of radioactive material into...Facility ventilation systemsInhalation (internal) dose hazardInterruption of ‘normal life’Expensive cleanup costsWater suppliesHigh dilutionIndividually significant doses would not likely result.The general environment (“dirty bombs”, crop dusters, fire, sprayer, etc..)Low likelihood of acute radiological effectsMay require population shelter or evacuationMay be difficult to clean outdoor areas
9Radioactive Material Production, Transportation, Use, and Possible Misuse WHAT IS A ‘DIRTY BOMB’?A “Dirty Bomb” is conventional explosives combined with radioactive material with the intention of spreading the radioactive material over a relatively large area.This is NOT a nuclear explosion, the radioactive material does not enhance the explosion.Very few deaths would be expected from acute radiological exposure (the greatest hazard would likely be from the effects of the conventional explosives).The contamination will hamper emergency response efforts and can delay hospital treatment.Widespread contamination can deny the use of facilities and areas and have a significant psychological impact on the exposed population.
10Radioactive Material Production, Transportation, Use, and Possible Misuse External ExposuresFocused radiation or localized contamination can result in radiation effect to specific areas on the bodyWhole body exposure can result from:A passing radioactive cloud or smokeA large, distant point sourceExposure from contamination deposited on the ground
11Radioactive Material Production, Transportation, Use, and Possible Misuse Internal ExposuresOnce radioactive material is deposited in the body, it can expose the person from within.The magnitude of the dose will depend on many factors:How much material was deposited,how it got into the body (ingestion, inhalation, absorption, or injection),chemical form of the radioactive material,the radiation it produces,how quickly it decays, andhow quickly the body eliminates the material.
12Radioactive Material Production, Transportation, Use, and Possible Misuse The Human FactorConcerns about radiation and contamination often produce an exaggerated emotional response.Can’t detect it with our 5 sensesAssociated with cancerReminiscent of “cold war” fearsScience difficult to understandOut of our controlPossible results may be…Unexposed people saturating the medical communityHealth and economic effects from long term anxiety or depression in the community
13Conclusion: Misuse of Radioactive Material Radioactive Material Production, Transportation, Use, and Possible MisuseConclusion: Misuse of Radioactive MaterialHigh activity sources can cause health effects, but only to those in close proximity.Acute health effects from distributed radioactive material unlikely without prolonged, high-concentration exposure.Radiation or contamination will hinder response efforts.Denial of facilities and areas will have a major cost effectPublic anxiety and its effects may be the primary lasting health effect.
