LMRT Safety Core Questions With Complete Solutions x-ray production requirements - Correct Answers ✅vacuum tube, source of electrons, high voltage, target The source of free electrons is - Correct Answers ✅The electron cloud (space charge) formed by thermionic emission.Acceleration of electrons - Correct Answers ✅A high- voltage electric source provides acceleration of electrons. A high positive electrical potential at the target attacks the negatively charged electrons Bremsstrahlung radiation - Correct Answers ✅"Braking radiation." The sudden deceleration of electrons as they interact with highly positively charged nuclei.Characteristic radiation - Correct Answers ✅created when an incoming electron interacts with the K-shell electron and knocks it out of orbit. When the electron void is filled with an outer shell electron, an x-ray photon is created Focusing of electrons (focusing cup) - Correct Answers ✅The shape of the focusing cup and its negative electric charge causes the electrons to be repelled in the direction of a very precise area on the target called the focal spot.deceleration of electrons - Correct Answers ✅X-rays are produced due to the sudden deceleration of fast-moving 1 / 2
LMRT Safety Core Questions With Complete Solutions electrons when they collide and interact with the target anode Wavelength - Correct Answers ✅distance from one crest to the next. The shorter the wavelength, the higher the frequency.Frequency - Correct Answers ✅number of times per second that a crest passes a given point.Quality (of x-ray beam) - Correct Answers ✅The mean energy or penetrating ability of the x-ray beam; the quality of the x-ray beam is controlled by kilovoltage.Quantity (of x-ray beam) - Correct Answers ✅the number of x-rays produced from the tubehead; the quantity of x-rays produced is controlled by millamperage.Primary radiation - Correct Answers ✅x-ray beam after it leaves the x-ray tube and before it reaches the object Remnant radiation (exit radiation) - Correct Answers ✅refers to the primary beam that exits the patient and is responsible for the formation of the image.inverse square law - Correct Answers ✅I1/I2=D2^2/D1^2
