where HT is the equivalent dose in tissue T and WT is the tissue weighting factor for tissue T.
"equivalent dose" means the quantity HT,R , defined as:
where DT,R is the absorbed dose delivered by radiation type R averaged over a tissue or organ T and WR is the radiation weighting factor for radiation type R.

(1) Except as provided in regulation 12(4) and regulation 13 any legal person intending to engage in a practice or possess a radiation source shall apply to the Board for an authorisation which shall take the form of either a registration or a licence.
(2) If the application referred to in subregulation (1) refers to an industrial irradiation installation, an installation processing radioactive substances, a medical or industrial radiography facility, or for any use of a source which the Board has not designated as suitable for registration, the authorisation shall take the form of a licence.
