# 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:

â€ƒâ€ƒNumberÂ ofÂ deathsÂ =Â 200Ã—10-4perÂ SvÂ ofÂ radiationÂ perÂ yearExtraÂ radiationÂ receivedÂ =Â 0.05Â mSvÂ =Â 5Ã—10-5Sv

Formula used:

Calculation:

Population of Australia = 24 million =24Ã—106

â€ƒâ€ƒNumberÂ ofÂ deathsÂ perÂ yearÂ =Â Population&#
