>Mike,

 The main NRC reg I know of is 10CFR part 35.59 which covers leak testing
(wipe sample) from the surfaces of the device. This procedure is not to
exceed every 6 months.  That is if you irradiator contains more than 100
microcuries of beta or gamma emitting material.  As for the operation of the
unit I know of nothing regulatory wise that stipulates who can operate it.
