IsoPet Solutions is a subsidiary of Advanced Medical Isotope Corporation. Advanced Medical Isotope Corporation and IsoPet will have no Cesium-131 product! I believe you are confused. I was referring to a previous post by someone asking about another firm being interested in buyout of Advanced Medical Isotope Corporation. This company that only has Cesium-131 product is located right in the same geographical proximity of Advanced Medical Isotope Corporation and they focus on Cesium-131. I don't understand your question because it isn't relevant and doesn't make sense. Advanced Medical Isotope corporation is not working closely with them at all, they have nothing to do with yttrium-90! I don't know who or what company you are thinking about. Maybe you are thinking of Iso therapeutics?
If you want to do some more due diligence in the brachytherapy market, look at Haakon Ragde and all the positive stuff he has done in this area of excellence. He is a pioneer in the brachytherapy market like Dr. Alice Villalobos is in the Vet radiation cancer market.
I didn't want to post this evening because I have better things to do but your post needed a clarification. Hope this answers it. If not, it can wait for another day but none of your questions are relevant. Maybe you confused IsoPet with Iso ray but Iso ray is not working anything with Advanced Medical Isotope Corporation or IsoPet.
Hope you have a good evening.
