jr chem techs for utilities get around 14 to 18 or so per hour.
ALARA eng- see those mostly at operating plants- but process facilities use them also. with process facilities critical arrays are a big deal, not so with utilities. beta/gamma and very little neutron is the concern with power plants. what they do- shielding calculations/ engineering load calcs; reduction planning, goal setting, new technology review, job planning etc. report writing.
rad engineers- that can be any thing- ALARA, MARSSIM, FSS, process management, waste management, crit controls, procedure write, effluent, NPDES, report write, graphics, RCRA, CERCLA, and any thing your degree set you up for.
CHP- they sign stuff, dose assessment, reports, program management, validation of programatic goals, setting of program goals, higher tier stuff.
