As with each of the trades, ELT may offer challenges that the others do not. I have qualified all that I can in the navy's nuke field and have an earned respect for all my fellow nukes (except the sluggards).
ELT may involve Radcon but do not fret. Radcon is not the hardest thing that you might do. Try catching a grape that was spit across the crews mess with only your mouth.... try sleeping on a frozen mattress.... or removing EB Green from body parts.
As an ET I pulled end bells and bearings off MG sets, changed risics and impellers on pumps and even had to perform primary/secondary chemistry analysis. But I always loved the challenge of an actual reactor recovery or going from single to two loop ops....
Good luck, work hard and thank you for your service.
