Question

1- You are a brown trout living in a high alpine lake in Colorado. You have a cousin (a rainbow) living in a farm pond next to the Department of Energy's Hanford Site. Describe why your annual radiation doses might differ?

2- Describe why they might be the same.

3- A human baby and an adult both drink milk containing 131I; both drink 1 L d-1. Which would you expect to have the higher concentration of 131I in their thyroid? Why?

4- 3H is detectable in the environment. Where did it come from?

5- An elephant and an amoeba both went for a swim in a pond contaminated with 137 Neither of them drank the water. Which would you expect to have the highest concentration of the contaminant? Why?

6- A mule deer is consuming vegetation from a contaminated pasture. The vegetation has an average activity concentration of 1 Bq g-1 of 137 Assuming the deer eats 1.5 kg d-1 and that the effective half-time for 137Cs in the deer is 500 days.   What equation would you use to calculate the activity in the "deer" compartment with time? Generate a plot (using excel or by hand) and submit it with your answer.

Explanation / Answer

1. The annual radiation dose differ because of the difference in the radiation with respect to altitudes. Higher altitudes are proven to have increased radiation in comparison with the ground level. Hence Brown trout living at high alpine lake will have more annual radiation than his counter part.
