what are the 4 essential elements required for x-ray production?
234963
There are four essential requirements for the production of x-rays: (1) a vacuum, (2) a source of electrons, (3) a target, and (4) a high potential difference (voltage) between the electron source and the target.

They include calcium, phosphorus, magnesium, sodium, potassium, chloride and sulfur. You only need small amounts of trace minerals. They include iron, manganese, copper, iodine, zinc, cobalt, fluoride and selenium. Most people get the amount of minerals they need by eating a wide variety of foods.

2.  X-radiations (or x-rays) is a form of electromagnetic radiations. Most x-rays have a wavelength of 0.01-10 nanometeres, corresponding frequencies in the range of 30 petahertz(3X10¹⁶ Hz) to 30 exahertz(3*X10¹⁹Hz) and energies in the range of 100eV to 100 keV.

Properties of X-Rays They have a shorter wavelength of the electromagnetic spectrum. Requires high voltage to produce X-Rays. They are used to capture the human skeleton defects. They travel in a straight line and do not carry an electric charge with them. They are capable of travelling in a vacuum.

There are two types of X-ray generated: characteristic radiation and bremsstrahlung radiation.
