If you want clarity on the requirements for NRRPT and CHP then just simply do a search on the internet for them. I believe each has its own website outlining their criteria for acceptance and deadlines for testing too. I also agree to get the NRRPT cert first, but dont overlook actually heading up programs for safety or auditing, etc so that later on you can point to evidence of your qualifications. If I am not mistaken for CHP that is the only role they consider, so past ELT exp will not be credited since it is probably considered at the technician level, though if you were a CRA or equivlent then you'lll probably be considered as leading a rad safety program.......Seems odd though my CRA's were typically told where and what to sign and they rarely involved themselves too much with the Div. Sorry, off subject...consider a Masters in health or medical physics since addtl education can be credited for experience though there is a cap on that. I am sure in no time that time window will approach and hope you wont be to busy to still pursue your goals. I feel that way all the time with this stuff....job, kids, ....Always stay focused.
