Cardiovascular (CV)/ Central Nervous System (CNS) syndrome: the full syndrome will usually occur with a dose greater than approximately 50 Gy (5000 rads) although some symptoms may occur as low as 20 Gy or 2000 rads. Death occurs within 3 days.

When working with radiation What should you do?

How Can You Work Safely Around Radiation?

  1. Use time, distance, shielding, and containment to reduce exposure.
  2. Wear dosimeters (e.g., film or TLD badges) if issued.

What are the dangers of working with radiation?

The hazards Ionising radiations can cause dermatitis, burns, cell damage, cataracts and changes to blood. Microwaves and radio frequencies can cause heating of any exposed part of the body, infra-red rays can cause skin burns and cataracts and UV light can cause skin burns, skin cancer, conjunctivitis and arc eye.

Does radiation exposure go away?

Does any radiation stay in the body after an imaging exam? After a radiographic, fluoroscopic, CT, ultrasound, or MRI exam, no radiation remains in your body. For nuclear medicine imaging, a small amount of radiation can stay in the body for a short time.
