How much is one PTCA procedure equivalent to? - answer100 to 250 CXR's
What are the principles of radiation protection? - answer Time, Distance and Shielding
In regards to distance, how does the inverse square law protect from radiation? -
answer The intensity of the exposure declines by the inverse square of the distance
from the primary beam.
Shielding - answer Blocks passage of ionizing radiation through to the body.
Equipment and methods used to reduce radiation penetration into the body - answer

Thyroid collars
Lead-lined eyewear
Strategically placed lead shields and drapes
What does TLD mean? - answerThermal Luminescent Dosimeter
Who maintains dosimetry records? - answerRAD safety at the hospital

the crystals allow us to see a difference in the crystal structure( lattice) which resulted
from the ionizing radiation bouncing electrons or leaving holes when it impacted the
crystal.
Target Molecule Theory - answerImportant parts of the cell (DNA) are target which
destroys the whole cell.
Indirect effect of radiation - answerThe interaction of ionizing radiation with non-critical
molecules, which transfer the energy of the ionizing radiation to a target molecule.
How often is datat collected from the TLD? - answerMonthly
What document is used to record mREM? - answerDD1141
