Iodine 131

Cesium 137

Strontium 90

Plutonium

Absorbed by the thyroid, as it is unable to determine the difference between normal and radioactive iodine. It causes cancer and other disorders in the thyroid gland.

The body is fooled into thinking this element is calcium. It gets absorbed into bones and causes leukemia and many other cancers, as well as deformities of the skeletal system.

Mistaken for potassium by the body, which is needed in every living cell. It then concentrates in muscles.

The most toxic substance known to man, Plutonium does not exist in nature. It is absorbed into the blood system and causes varieties of cancers and blood disorders.

Voices From Chernobyl

• “He was producing stool 25-30 times a day. With blood and mucous. His skin started cracking on his arms and legs. He became covered with boils. When he turned his head, there’d be clumps of hair left on the pillow.”

• “I changed the sheet on him every day, and by evening it would be covered in blood. I pick him up, and there are pieces of skin on my hand”

• “Pieces of lung, his liver were coming out of his mouth”

What Do You Think This Means?

• “Chernobyl is like the war of all wars. There’s nowhere to hide. Not underground, not underwater, not in the air.”
