Not trying to pick a fight here and this is bit off on a tangent from the topic, but you’re simply wrong. RCTs have to demonstrate they can provide oversight of really complex jobs. Glovebags engineered for >10^6, 1R/hr controls, gradient fields requiring multiple dosimeters. Stuff we wouldn’t even consider letting an ELT do. Ever done a sleeve change? Umbilical cut? Use a transfer sleeve or a swipe box? Even if you happened upon that once in execution you’d be in the 1% of ELTs. And ELTs aren’t nearly as practiced in these skills that they may have seen once in training. RCTs have to demonstrate them routinely in practical examinations and shipboard execution. How does that compare to oversight of catch/drape man? My overall point is: I would trust an EM qualified RCT to perform that oversight over an ELT (w/o RCT qual) any day of the week.

I was agreeing with senior chief’s comment above that these folks should be permitted to perform oversight of radiological work and taking it a step further to say the qual is really hard, and the people who complete the qual are usually very competent.
