      (i) Notwithstanding other requirements for notification, each registrant shall immediately report each event involving a radiation machine possessed by the registrant that may have caused or threatens to cause an individual to receive:

        (I) a total effective dose equivalent of 25 rems (0.25 Sv) or more;

        (III) a shallow dose equivalent to the skin of the whole body or to the skin of any extremities of 250 rads (2.5 grays) or more.

      (ii) Each registrant shall, within 24 hours of discovery of the event, report to the agency each event involving loss of control of a radiation machine possessed by the registrant that may have caused, or threatens to cause an individual to receive, in a period of 24 hours:

        (I) total effective dose equivalent exceeding 5 rems (0.05 Sv);

        (II) lens dose equivalent exceeding 15 rems (0.15 Sv); or

        (III) a shallow dose equivalent to the skin of the whole body or to the skin of any extremities exceeding 50 rems (0.5 Sv).
