Which type of radiation is created when the primary beam interacts with matter?
Primary radiation is the x-rays that come from the target of the x-ray tube. Secondary radiation is x-radiation that is created when the primary beam interacts with matter. Scatter is a form of secondary radiation. It results when an x-ray beam has been deflected from its path by interaction with matter.

What is the purpose of the collimator?
Collimator, device for changing the diverging light or other radiation from a point source into a parallel beam. This collimation of the light is required to make specialized measurements in spectroscopy and in geometric and physical optics.
Which of these types of radiation has the greatest penetrating power?
Gamma radiation
Which type of radiation is a high energy electron?
X-Rays. X-rays are similar to gamma radiation, with the primary difference being that they originate from the electron cloud. This is generally caused by energy changes in an electron, such as moving from a higher energy level to a lower one, causing the excess energy to be released.
What is the good effect of electromagnetic radiation?
These include nerve regeneration, wound healing, graft behavior, diabetes, and myocardial and cerebral ischemia (heart attack and stroke), among other conditions. Preliminary data even suggest possible benefits in controlling malignancy.
Can a pinched nerve in the neck cause ringing in the ears?
Overactive nerves in head and neck may account for ‘ringing in the ears’ Do your ears ring after a loud concert” Nerves that sense touch in your face and neck may be behind the racket in your brain, University of Michigan researchers say.
