If everyone in Australia received an extra 0.05 mSv per year of radiation, what would be the increase in the number of cancer deaths per year? (Assume that time had elapsed for the effects to become apparent.) Assume that there are 200 × 10 − 4 deaths per Sv of radiation per year. What percent at the actual number of cancer deaths recorded is this?

To determine

What would be the increase in the number of cancer deaths per year if everyone in Australia received an extra 0.05 mSv per year of radiation? (Assume that time had elapsed for the effects to become apparent.) Assume that there are 200×104 deaths per Sv of radiation per year. What percent of the actual number of cancer deaths recorded is this?

Explanation

Given info:

Number of deaths = 200×10-4per Sv of radiation per yearExtra radiation received = 0.05 mSv = 5×10-5Sv

Formula used:

Number of deaths per year = Population×Radiation received×Number of deaths per Sv of radiation per year

Calculation:

Population of Australia = 24 million =24×106

Number of deaths per year = Population&#
