"effective dose" means sum of the weighted equivalent doses in all organs and tissues of the body calculated using the formula -
E=wT HT where -
E is the effective dose; wT is the tissue weighting factor for the organ or
tissue T;
HT is the equivalent dose in the organ or tissue T;
"effective dose limit" means dose limit specified in
item 1 (1), (3) or (4) of Schedule I;
"equivalent dose" means the sum of the weighted absorbed doses in an organ or tissue calculated using the formula -
HT = I w DTR

11T is the equivalent dose in the organ or tissue T;
wR is the radiation weighting factor for the
radiation R;
DTR is the absorbed dose from the radiation R
averaged over the organ or tissue T;

that have been taken temporarily to that site;
"radiation weighting factor" means factor set out in
Table 1 of the publication entitled "Recommendationsfor limiting exposure to ionizing radiation (1995)", approved by the NHMRC in June 1995, which
modifies the absorbed dose in an organ or tissue to
