VERIFIED CORRECT ANSWERS |
ALREADY GRADED A+ |
GUARANTEED PASS
Gamma and X-Radiation can be detected by which human senses? - ANSWER-
None — gamma and X-radiation cannot be detected by sight, touch, smell, taste, or
hearing; an instrument is required to detect them
A device with a sealed source that may be moved for making a radiographic
exposure is called a(n): - ANSWER-Exposure Device
Pocket dosimeters used in industrial radiography should have a range from: -
ANSWER-0 to 200 mr
, Delayed effects of radiation exposure can include: - ANSWER-Cancer and Genetic
Defects (1 and 3)
The penetrating ability of Gamma or X-Radiation is determined by the: -
ANSWER-Energy level, KeV or MeV
If a pocket dosimeter is damaged or loses charge, the dose readings will usually be:
- ANSWER-Falsely High
A radiation dose over a long period of time will: - ANSWER-Have a lesser
biological effect than the same dose received over a shorter period of time
Radioactive material permanently fixed in a capsule to prevent release/dispersal is
called: - ANSWER-A Sealed Source
If 1/2" thick lead is placed in the path of a beam from a Co-60 source, it will
reduce the dose rate by approximately: - ANSWER-1/2
Radiation effects which appear years following exposure are called: - ANSWER-
Delayed Effects
Ir-192 sources used for industrial radiography usually have activities in the range
of: - ANSWER-25 to 100 Cis
The maximum annual occupational dose permitted for a 25 year old radiographer
is: - ANSWER-5 Rem
