First of all, medical reactors are NOTHING like energy producing nuclear reactors, they are tiny, use so little fissile material as to render them totally safe, and are so well accepted that we have 2 in our city, both housed in hospitals (for in-house production of ALL of their nuclear tagged isotope needs.)
You all should do some DD. I picked this up on my watch list after the Seeking Alpha article a couple of months ago. GO READ THE LAST ANNUAL REPORT! It's a real eye opener. In addition to the back-in incorporations that have occurred over the years, AND the one customer they have in WA (for isotope product), their revenue is paltry and 90% of the revenue came from "consulting" fees in 2011, meaning they sold all of about $50K in product. Not very encouraging for them.
Medical reactors can be small cyclotrons, BUT the only one in the USA that could be used today is the MURR one in Columbia, Mo. None of the small ones made today can
produce sufficient (if any at all, it is not proven) Mo-99 for its derivative, Tc-99m. So while you are partially correct, you are significantly off in thinking that all of the medical isotope demand can be produced by the small ones at local urban hospitals.
You should read the more current quarterly statements of the company to get a better picture of its financial strength and client base.
