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 |
| 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 |
