The responsibility for maintaining radiation monitoring records for all personnel
and for providing counseling for individuals who receive monitor readings in
excess of allowable limits belongs to the
Designated radiation safety officer of a health care facility.
As the intensity of x-ray exposure of the air volume increases, the number of
electron-ion pairs produced
Also increases.

For x-ray and gamma ray photons with energies up to 3 million electron volts
(mev), which of the following radiation quantities may be defined as the measure
of the total electrical charge of one sign, either all pluses or all minuses, per unit
mass that these two types of radiation generate in dry air (i.e., nonhumid) at
standard temperature and pressure (760 mm Hg or 1 atmosphere at sea level and
22° C)?

The essential concept underlying radiation protection is that
Any organ in the human body is vulnerable to damage from exposure to ionizing
radiation.
