Units of Absorbed Dose

Description

 • Absorbed dose has the dimension absorbed dose of radioactive energy per mass. The SI derived unit of absorbed dose is the gray, which is defined as a joule of absorbed radiation per kilogram.
 • Maple knows the units of absorbed dose listed in the following table.

 Name Symbols Context Alternate Spellings Prefixes gray Gy SI * grays SI rad rd radiation rads, gram_rad, gram_rads

 An asterisk ( * ) indicates the default context, an at sign (@) indicates an abbreviation, and under the prefixes column, SI indicates that the unit takes all SI prefixes, IEC indicates that the unit takes IEC prefixes, and SI+ and SI- indicate that the unit takes only positive and negative SI prefixes, respectively.  Refer to a unit in the Units package by indexing the name or symbol with the context, for example, gray[SI] or rad[radiation]; or, if the context is indicated as the default, by using only the unit name or symbol, for example, gray or gram_rad.
 Note: The default context of the rad is angle, relating to a measurement of angle not absorbed dose.
 The unit of absorbed dose is defined as follows.
 A rad is defined as an erg of radiation per gram or $\frac{1}{100}$ gray.

 $\frac{{{\mathrm{length}}{}\left({\mathrm{radiation}}\right)}^{{2}}{}{\mathrm{mass}}{}\left({\mathrm{radiation}}\right)}{{\mathrm{mass}}{}{{\mathrm{time}}{}\left({\mathrm{radiation}}\right)}^{{2}}}$ (1)
 > $\mathrm{convert}\left(1,'\mathrm{units}','\mathrm{Gy}','\mathrm{rad}\left[\mathrm{radiation}\right]'\right)$
 ${100}$ (2)
