'IAEA publications', the term 'radiation' normally refers only to <br/>
'ionizing radiation'. The IAEA has no statutory responsibilities in relation to <br/>non-ionizing 'radiation'.<br/>'Ionizing radiation' can be divided into 'low linear energy transfer radiation' and <br/>'high linear energy transfer radiation' (as a guide to its <i>relative biological <br/>effectiveness</i>), or into 'strongly penetrating radiation' and <i>weakly penetrating <br/>radiation</i> (as an indication of its ability to penetrate shielding or the human <br/>body).<br/>
<i><b>high linear energy transfer radiation.</b></i> 'Radiation' with high <i>linear energy <br/>transfer</i>, normally assumed to comprise protons, neutrons and alpha <br/>particles (or other particles of similar or greater mass).<br/>
These are the types of 'radiation' for which the International Commission on <br/>Radiological Protection recommends a 'radiation weighting factor' greater <br/>than 1.<br/>Contrasting term: 'low linear energy transfer radiation'.<br/>
<i><b>ionizing radiation.</b></i> For the purposes of 'radiation protection', <i>radiation<br/></i>capable of producing ion pairs in biological material(s). (From Ref. [1].)<br/>
<i><b>low linear energy transfer radiation.</b></i> 'Radiation' with low <i>linear energy <br/>transfer</i>, normally assumed to comprise photons (including X rays and <br/>gamma 'radiation'), electrons, positrons and muons.<br/>
These are the types of 'radiation' for which the International Commission on <br/>Radiological Protection recommends a 'radiation weighting factor' of 1.<br/>
<i><b>strongly penetrating radiation.</b></i> 'Radiation' for which 'limits' on <i>effective <br/>dose</i> are normally more restrictive than 'limits' on 'equivalent dose' to any <br/>tissue or organ, i.e. the fraction of the relevant 'dose limit' received will, for <br/>a given 'exposure', be higher for 'effective dose' than for 'equivalent dose' to <br/>any tissue or organ. If the reverse is true, the 'radiation' is termed <i><b>weakly <br/>penetrating radiation</b></i>.<br/>
For most practical purposes, it may be assumed that <i>strongly penetrating <br/>radiation</i> includes photons of energy above about 20–30 keV, high energy <br/>electrons (more than about 1–2 MeV) and neutrons, and that <i>weakly <br/>penetrating radiation</i> includes photons of energy below about 20–30 keV, beta <br/>particles and other electrons of less than about 1–2 MeV, and massive charged <br/>particles such as protons.<br/>Contrasting term: 'weakly penetrating radiation'.<br/>
