6. Labelling
(1) No person shall store or convey, or cause or permit to be stored or conveyed, any container containing any radioactive substance unless such container bears—
(a) in the case of any container in respect of which the dose rate of the radiation at any point on the external surface of the container does not exceed—
(i) 2.5 microcoulombs per kilogram per 24 hours in the case of gamma or X radiation;
(ii) the equivalent of 2.5 microcoulombs per kilogram per 24 hours in the case of beta-radiation; or
(iii) those values of flux given in Table I to this regulation in the case of neutrons,
a label in the form of Label A prescribed in the Schedule (in this Part referred to as a White Label);
(b) in the case of any container in respect of which the dose rate of the radiation at any point on its external surface exceeds the limits specified in paragraph (a) but does not exceed at any such point—
(i) 50 microcoulombs per kilogram per hour in the case of gamma or X radiation;
(ii) the equivalent of 50 microcoulombs per kilogram per hour in the case of beta-radiation; or
(iii) those values of flux given in Table II to this regulation in the case of neutrons,
or if measured at a distance of 1 m from any point on the external surface—
(iv) 2.5 microcoulombs per kilogram per hour in the case of gamma or X radiation;
(v) the equivalent of 2.5 microcoulombs per kilogram per hour in the case of beta-radiation; or
(vi) those values of flux given in Table III to this regulation in the case of neutrons,
a label in the form of Label B prescribed in the Schedule (in this Part referred to as a Yellow Label).
(2) For the purposes of subregulation (1), the limits for dose rates referred to for each type of radiation shall be deemed to be equivalent in biological effectiveness.
