Only if you want to be stuck in the corner of a dark CP somewhere plotting contamination fields and using software to model downwind hazards. Lots of reports and returns in and out of the CBRN Cell. Fun for some I guess. Important work, but the largest problem with the course is that the skill set is very perishable and once you complete the training if you are not using it regularly (rare) you will lose the edge, especially with the computer program.
If you want to get a feel for some of this stuff then look at NATO ATP 45, for which the CBRN Operation Centre Operator is the CAF wizard. I cannot find an open source version, but the US Field Manual has much of the same info and will give you a feel for the topic. Google "US FM 3-11.3". You have found it if it is called Multiservice Tactics, Techniques, and Procedures for Chemical, Biological, Radiological, and Nuclear Contamination Avoidance.
Likely some transferable skills to the real world, if you want to get into this sort of work (albeit very specialized and limited).
You will be less fun at parties with this qualification on your MPRR.
