Mr. Speaker, again, as we deal with the shortage of Tc99, alternatives are available.
Let me repeat what I said yesterday. Fifty per cent of the uses of Tc99 isotopes are for heart scans. Thallium can be used as an alternative in many of these cases, and that is available now. The next largest use of Tc99 isotopes is for bone scanning. Again, there is an alternative, sodium fluoride, which can be used in these cases, and it is available now.
These alternatives were identified by medical experts on isotopes and we are making sure they are available.
