3. Shorter by approximately 55 percent

Kilovoltage is the voltage at its peak that is given to the x-ray tube. It may seem scary to know that these kilovoltage have radiation and that may be exposed to the patient who is getting the x-ray done. The electrons in the x-ray are increased in speed and therefore move faster. They move to the anode from the cathode. X-ray photon is in the x-ray and the kilovoltage decides at what point is the most energy used for this photon. There are certain known facts about what the changes of the x-ray will do. One is with making the wavelengths of the x-rays shorter. As a result, there will be less penetrating power produced. It is up to the x-ray technician to make these determinations.

D.Greater than 99% of the kinetic energy imparted on the electron beam is lost in the form of heat at the anode target. https://xray.oxinst.com/application-notes/managing-the-heat-produced-by-x-ray-tubes

The answer to this is B. Some people do not even know what Roentgen is. This is also known as rontgen. This is a type of measurement that is associated with gamma rays. This is something that cannot be avoided when people need to get Xrays but there are some who may try to avoid their exposure to it because of their belief that it can cause cancer. It would take an exposure of about 1000 sievert in order to cause cancer. For example, someone who has gone through a CT scan more often for a short period of time may be at a greater risk of acquiring cancer as compared to someone who has not gone through a CT scan at all.

Primary radiation, as its name suggests is the main radiation that occurs when using an x ray machine. Scatter radiation is the secondary radiation that is produced as a result of the primary radiation. A third type of radiation exists called leakage radiation. This is all the radiation that leaks out when the x ray machine is being used and scatters everywhere other than the focus point of the primary beam. When tin foil comes in direct contact with an x ray film it intensifies the primary radiation more than the scatter radiation.

Decrease exposure time

All the options listed above are characteristics of X ray Photons/bundles of energy: X rays make up x radiation just light every other electromagnetic radiation. They can be produced in parcels of energy called photons. X rays have high penetrating power, they have shortwave length and these rays can easily penetrate our body. X rays are invisible; they cannot be seen, felt or heard. They possess no charge and no mass. X rays are similar to light waves and they travel at a speed of light in a vacuum. X rays travel in a straight line, differ in their source of origin and they also have different energies, the wavelength ranges from 0.01 to 10 nanometers.

The latent image refers to the image that can't be seen until it is developed.

Incident radiation liberates electrons which help to expose the film

Radiation should proceed from as small a focal spot as other considerations will allow
