The International System of Units, or the SI units (shortened from the French Système international d’unités) is the globally-adopted system of units of measurement. It is the modern iteration of the metric system.
What is ΜGY?
A microgray (µGy) is a decimal fraction of the SI-derived unit of absorbed dose and specific energy (energy per unit mass). Such energies are usually associated with ionizing radiation such as gamma particles or X-rays. In the SI basic units, a gray is expressed as m²⋅s⁻².

What is the value of 1 x ray unit?
The x unit (symbol xu) is a unit of length approximately equal to 0.1 pm (10−13 m). It is used to quote the wavelength of X-rays and gamma rays.
What is a GREY in radiation?
One gray (Gy) is the international system of units (SI) equivalent of 100 rads, which is equal to an absorbed dose of 1 Joule/kilogram. An absorbed dose of 0.01 Gy means that 1 gram of material absorbed 100 ergs of energy (a small but measurable amount) as a result of exposure to radiation.
