Suppose 10 million people are exposed to a carcinogen that poses an individual lifetime (70-yr) cancer risk of 10^-4. (a) How many cancers per year might be caused by this carcinogen? (b) If spending $1 per year per person (for an indefinitely long time) to reduce exposure to that carcinogen reduces that risk to 10^-5, what would be the cost of each cancer avoided?

Question
Suppose 10 million people are exposed to a carcinogen that poses an individual lifetime (70-yr) cancer risk of 10^-4.
(a) How many cancers per year might be caused by this carcinogen?
(b) If spending $1 per year per person (for an indefinitely long time) to reduce exposure to that carcinogen reduces that risk to 10^-5, what would be the cost of each cancer avoided?
Expert Solution
Step 1
Given
Lifetime = 70 years
Risk = 10-4cancer/person
Population = 10 x 106 people
To find
(a) Cancer rate per year
(b) Cost for each cancer avoided
