“…3. As a results, the half-life of 99m Tc with the chemical form of KTcO 4 is determined to be (6.0016 ± 0.0053) h, which is in good agreement with recent values of other authors which were measured with the chemical form of pertechnetate ((6.0072 ± 0.0010) h in normal saline solution [8] and (6.0071 ± 0.0021) h in NaTcO 4 [5]).…”

We have produced 90mNb and 99mTc in the reactions of natZr(p,xn)90mNb and 100Mo(γ,n)99Mo, followed by disintegration to 99mTc, respectively, and measured the half-lives of these nuclides by using a reference source method. In order to determine the short half-lives of 90mNb precisely, an on-line gas-jet system has been employed. As a result, the half-lives of these nuclides were determined with good precision on the order of magnitude of 0.1%.

“…In November 2017, a standard NIST 5 mL flame-sealed ampoule containing 5 g of solution was obtained from the NIST Radioactivity Measurement Assurance Program (NRMAP) [22] and measured on multiple dose calibrators. The standard activity was taken from secondary standard ionization chamber (SSIC) measurements on NIST Chamber “A” (ICA) [23] using the calibration factor (“ K -value”) determined in 1976 [24]. The primary standardization used coincidence counting with a pressurized proportional counter/NaI(Tl) system.…”
