Joule
The Joule (J) is the SI unit of energy. One Joule is the energy expended when a force of one newton is applied over a displacement of one meter in the direction of the force. The use of the joule is probably limited in Radiation Protection
but is used in the definition of Absorbed Dose
and the Electron volt
.
Justification
Justification is one of the first three principles of the ICRP
system of radiological protection. Justification, together with Optimisation
and Limitation
, are used as the basis of Radiation Protection
internationally. Justification is defined in the ICRP 60 publication as 'no practice involving exposures to radiation should be adopted unless it produces sufficient benefit to the exposed individual or to society to offset the Detriment
it causes'.
