Chemical Hazards and Reactions

External Radiation Protection Factors

• Time: Reducing the amount of time in a radiation field reduces the amount of exposure.
• Distance: Increasing the distance between you and a radioactive material decreases the intensity of the hazard.
• Shielding: The greater the mass situated between you and a radioactive material, the less radiation that will penetrate.
• As Low As Reasonably Achievable (ALARA): Keeping radiation exposure as low as reasonably achievable can reduce unnecessary occupational exposure.
