matter is _______.
linear energy transfer
relative biologic effect
indirect action
direct action
Give this one a try later!
linear energy transfer
The use of additional filtration in a therapeutic x-ray machine is primarily intended to:
Increase beam quality

shielding
Give this one a try later!
exposure
The test that will check the uniformity of dose from one side of the field to the other is
called:
Beam symmetry
Split field test
Beam flatness
Light/beam coincidence
Give this one a try later!
