None of the above.

The radiological danger from plutonium is greater than its chemical toxicity.
False
True

When a thermal neutron is captured by Li-6, what 2 atoms are produced?
Deuterium and Uranium
Tritium and Helium (alpha particle)
Hydrogen and Helium
All of the above

Why do we need to measure neutrons to detect plutonium?

Neutrons are not easily shielded.
The neutron background is low and relatively constant globally.
There are fewer legitamate reasons to possess a neutron source.
The other radiation from plutonium decay is easy to shield.
All of the above.
