Radioactive Specimens identification and geology

Some rocks and minerals contain naturally occurring radioactive material NORM . These materials can expose workers to radiation and may also release radon gas in enclosed spaces. Risk depends on the specimen, how it is stored, and how often it is handled. Use time, distance, and shielding to reduce exposure. Store specimens in sealed, labeled containers with good ventilation practices in storage areas. Follow site rules for transport and disposal. This guidance is educational and is not a substitute for your employer's or site's safety training and rules. Do list: Label radioactive or suspected NORM specimens clearly, Store in sealed containers and use designated storage areas, Limit handling time and keep distance when possible, Keep storage areas ventilated and monitored if required, Follow transport rules for radioactive materials and samples. Dont list: Do not store NORM samples in offices, vehicles, or sleeping areas, Do not cut or crush radioactive samples without a safety review, Do not ship NORM samples without checking TDG and site rules, Do not ignore unusual readings or warnings from monitors, Do not let untrained people handle radioactive specimens. First aid: If contamination is suspected, stop handling and isolate the material. Wash hands and any exposed skin with soap and water. Report to the radiation safety contact and follow site monitoring procedures. Seek medical advice if directed by the safety program.. Regulations: In Canada, handling and disposal of NORM may be regulated by provincial/territorial governments, and transport/import/export follow CNSC requirements. Follow WHMIS/SDS and any site radiation safety program. Where applicable, refer to OSHA/MSHA radiation guidance.. Hazard level: high. Ppe required: nitrile gloves, safety glasses, lab coat or coveralls, personal dosimeter when required by site. Common geological settings: Uranium/thorium-bearing minerals, heavy mineral concentrates, some granites/pegmatites, core sheds with NORM zones, and storage rooms with many samples.

Sources, scope & corrections

These authoritative resources support category-level nomenclature, terminology, identification methods, and safety. When a specimen-specific safety warning appears, the public-health source listed here directly supports that precaution. They are not line-by-line citations for every other property on this entry, and natural specimens vary.
