Accelerator Production of the Medical Isotope Tc-99m

This talk will provide a broad overview of the present and future methods
for producing  99Mo which is used in about 80% of the estimated 80,000
nuclear medicine procedures performed daily in North America.  The main
part of the talk will focus on the production of 99Mo or 99mTc with
high-power accelerators.  99Mo can be produced with an electron linac using
the 100Mo(γ,n)99Mo reaction on a separated isotope 100Mo target.   99mTc
can be produced by using the 100Mo(p,2n)99mTc reaction and
isotope-production cyclotrons with proton energies from about 16 to 25 MeV.
A number of the technical challenges and the status of both approaches will
be reviewed.
