Answer 7

Radiological meter readings are ABOVE background from a LEGITIMATE source AND
the source HAS NOT been released from its container.
The sorce may also be a naturally emitting source.
Readings must be confirmed by a 2nd meter.

c) People who received medical radiological treatment

Question 9

What is a Radiological EMERGENCY?

Answer 9

Involves a source that is OUT OF its container, either accidentally or intentionally.
Meter readings are ABOVE what is expected for a specific location.
Readings MUST be confirmed by a second meter.

The MAXIMUM level of radiation at ONE METER from an UNDAMAGED package.

Question 29

What does the Transport Index apply to?

Answer 29
