Epithermal neutron activation analysis of short-lived radionuclides using a pneumatic transport system and a pulsed D-T neutron generator
… system for the detection and characterization of short-lived (of order 60 s or less) radionuclides produced during irradiation by a D-T neutron generator was constructed. Target samples of indium, palladium, and germanium were irradiated by the neutron generator embedded in a graphite monolith to …

… WAS ALSO DEVELOPED BASED ON THE MEASUREMENT OF SHORT-LIVED RADIONUCLIDES. THE CONCENTRATIONS OF NA, AL, K, CA, TI, V, MN, CO, EU AND DY WERE DETERMINED IN SAMPLES TAKEN FROM ROOF TILES FROM ANCIENT PELLA WHICH HAD BEEN PREVIOUSLY ANALYSED BY THE FIRST METHOD. THE RESULTS FROM THE TWO METHODS …

Multi-element isotopic analyses of presolar graphite grains from the Orgueil meteorite
… ratios, and the initial presence of the short-lived radionuclide <super>44</super>Ti in some grains. Some high-density grains also show supernovae signatures, but a majority seems to originate from low-metallicity asymptotic giant branch stars. Evidence for this comes from correlated …

Development of multifunctional compounds for the modulation and detection of amyloid beta species
… However, these radiolabeled agents are employing short-lived radionuclides, such as 11C and 18F (t1/2 = 20.4 min and 109.8 min), respectively), thus limiting their widespread use. Thus, the development of longer-lived radiolabeled compounds is essential for further expanding the use of PET imaging …
