Staff at MNR also prepare small (mCi) quantities of investigational radioisotopes for research purposes (see list below). Each radioisotope is dispensed in a high purity solvent, assayed, and issued a certificate of analysis.

Isotope Production Route Half-life Specific Activity Radionuclidic Purity Radiochemical Purity Concentration
Sodium-24 23Na(n,γ)24Na 15h > 1 mCi/mg >98% > 98% Na2CO3 10 mCi/mL
Potassium-42 41K(n,γ)42K 12.4h > 0.1 mCi/mg >98% > 98% K2CO3 10 mCi/mL
Copper-64 64Zn(n,p)64Cu 12.7d No carrier added >98% > 95% 1 mCi/mL
Arsenic-77 76Ge(n,γ)77Ge → 77As 1.6d No carrier added >98% >95% As3+ 10 mCi/mL
Iodine-131 natTe(n,γ)131/131(m)Te → 131I 8d No carrier added >98% 98% I- 1 mCi/mL
Holmium-166 164Dy(2n,γ)166Dy → 166Ho 26h No carrier added >98% N/A 10 mCi/mL
Holmium-166 165Ho(n,γ)→166Ho 26h >20 mCi/mg >99% N/A 100 mCi/mL
Thulium-170  169Tm(n,γ)170Tm 130d > 10 mCi/mg >98% N/A 50 mCi/mL
Rhenium-188/6 natRe(n,γ) + Szilard Chalmers 18h/3.7d 0.5-1.0 Ci/mg ~ 3:1 188Re:186Re > 95 % [ReO4]- 10 mCi/mL
