According to the EPA, what is an acceptable level radiation exposure? A.
3 in 10,000 have a risk of developing a fatal cancer
B.
3 in 1,000,000 have a risk of developing a fatal cancer
C.
10 in 30,000 have a risk of developing a fatal cancer
D.
10 in 3,000,000 have a risk of developing a fatal cancer

A) In 10,00 have a risk of developing a fatal cancer.

Explanation:

Risks that are low for an individual could still result in unacceptable numbers of additional cancers in a large population over time. For example, in a population of one million people, an average one-percent increase in lifetime cancer risk for individuals could result in 10,000 additional cancers. The EPA sets regulatory limits and recommends emergency response guidelines well below 100 millisieverts (10 rem) to protect the U.S. population, including sensitive groups such as children, from increased cancer risks from accumulated radiation dose over a lifetime.

the answer would be:

b. race
