Problem 8: Factors affecting dose


A family home has a clogged furnace that is producing carbon monoxide, a hazardous gas. Which family member is likely to be harmed the most?

A. Billy, the son who is in 1st grade
B. Baby Shea, who is going to be in preschool next year
The three important factors here are length of exposure, age and size. Baby Shea is most likely to be harmed because 1) he is the youngest and therefore smallest person in the house, and 2) along with his mother, Mrs. Nguyen, he spends the most time in the home.
C. Karla, the nanny who cares for the toddler every weekday morning
D. Ms. Nguyen, the mother who works at home
E. Mr. Nguyen, the father who works at the University
