1.a.

1.Why is it necessary to get back the stolen radioactive materials?
2.Why is Iridium not harmful after 72 hours?
3.What does the Sentinel model 660b look like?

ANSWERS:
1. Because prolonged exposure to these Radioactive materials pose possible danger to the people who are exposed to them.
2. Because it loses half of its activity
3. It looks like a "wooden shoeshine box," according to De la Rosa. She said it measures 12 1/4 inches by 4 1/4 inches by 9 1/2 inches.

b.

1. What is the radioactive camera's composition? (what is it made of?)
2. Can these incident be a major threat to the country?
3. How can I know if the people I am with are exposed to these materials?

2.a.

I would instruct the students to put down the materials and ask them to leave and go to somewhere where they can be left alone (Much like quarantine..), then I would call the parents of the students and tell them about these incident.

Lastly, I will attempt to isolate the materials in a confined room, using protective gear.

b.

In order to arrive at the ideal course of action, I need to know the effects of Nuclear Radiation, how to identify radioactive materials (The characteristics of radioactive substances) and how to handle these substances.
