By 1978,

Lhe amounts of radioactive things in peoples bodies were higher than
seientists had estimated when the people were

told

that

k-Ehey could

return.

This is the reason that they were removed from Bikini Atoll.

The way they measure these three things, they take

urine and measure the amount of things that are radioactive in it.

Fram doing

this they are able to estimate how much plutonium, americium, and strontium is
in a person's body.
