Internal Radiation Exposure Protection

  • Bad habits are the primary cause of accidental ingestion or inhalation of radioactive materials.


  • Seventy to eighty percent of accidental exposure to RAM is related to eating and drinking in the labs. Remember there is No Eating, Drinking or Smoking permitted in RAM labs.


  • Do not mix lab materials with food or drinks, either in the labs or in freezers or refrigerators.


  • Habits such as tobacco/gum chewing, application of cosmetics/chap stick, chewing on pens, or curling hair with your fingers are habits that increase the chance of personal contamination.


  • Never use lab ware for food or drinks.


  • Don't use food or drink containers for any HAZMAT. They are not designed for that purpose and could be accidentally ingested.


  • Example: An AUI was carrying 2 mCi of C-14 in a coffee cup. He stopped for a latte and put the cup down. He left with his latte and didn't realize he had left the C-14 at the coffee stand. Luckily the material was labeled and the RSO was called. The AUI, when called, was unaware of the fact the C-14 was left unsecured. His habit of always carrying one coffee cup led to this incident.
