Final answer:
The factors influencing X-ray production are filament voltage, current, and filament material.
Step-by-step explanation:
The three factors that influence X-ray production are voltage, current, and filament material. Specifically, the filament voltage is critical as it determines the acceleration of electrons towards the target material, which in this case, is usually made of copper. When these energetic electrons strike the anode of the cathode ray tube (CRT), they interact with the material and can produce photons of electromagnetic (EM) radiation, which are the X-rays. The current defines the number of electrons that reach the anode and thus impacts the intensity of the X-rays produced. Lastly, the filament material affects the efficiency of electron production. High voltage is necessary to produce X-rays with shorter wavelengths that have greater penetration abilities. The effects of ionizing radiation, such as X-rays, depend on the type of radiation, energy of particles, number of particles that interact with the matter, and the chemical nature of the substance exposed.
