From May until recent weeks, the impact has been approximately 50% of Canadian supply. Now, with the shutdown of the Dutch reactor, it is becoming increasingly difficult to predict exactly what the impact will be in coming weeks. So, the longer this shortage continues, the fewer alternatives we have. We do not have a plan B or a plan C. So we are at the mercy of various reactors.
I can tell you that we are looking everywhere to try to find everything available. To date, we have managed to find a significant share, between 40% and 50%. However, we are not producing molybdenum ourselves.
With regard to thallium, it's really a substitute product, recommended by Health Canada. So, at the request of doctors who want to use it, we reactivated our cyclotrons and we are meeting the demand... We feel that this is temporary, while we wait for technetium to become available once again.
I think that Dr. Turcotte gave a very good explanation of the advantages and disadvantages of thallium. I think that his medical expertise is far superior to mine. So, if you need other comments on this matter, I would prefer that he answer.
