Yes, with the CHP the only thing you could be unfamiliar with is lasers and x-rays, but they can send you to classes for that training--same for DOT haz shipping certification. They also have RSO classes, but you should not need that.
See 10CFR35 for RSO quals (it's for medical but it mostly applies and you did not specify if it was mainly a MEDICAL or an occupational health physics job) and maybe review 30 and 33 for broadscope license info.
Most of your university isotopes are pure betas if doing lab research (p32, s35, h3, and c14 are the most common), with some metastable gammas (tc99, ba137, co60, etc.) thrown in if they deal with medical research patients.
You should be able to demand a 100k+ salary if the position is at a sizeable univ. If the job is occupational health physics, it will be under the auspices of the EHS department, so try to find out what the other EHS division heads make, or what the EHS director makes. If it is a state univ, most salaries fall in a specified range and are either posted or you can contact HR. If it is a priv univ, it's all about how much they want you.
