Thank you very much.
Highly skilled nuclear researchers confirm I think what you just said, Mr. MacDiarmid, that the size of the facility for producing isotopes doesn't necessarily have to be as gargantuan as previously. I'm wondering whether within the realm of physics it is possible now for locations that have the concrete and the protection, such as cancer research centres or biomedical research facilities, to produce isotopes for the market safely. And do they have to be licensed by AECL? Do you have the monopoly on the franchise, or is there room for commercial competition in this?
