As aging nuclear reactors require increased maintenance, and even shut down completely, the strain on their production is being felt far beyond the energy industry: inside oncology and cardiac clinics. But help is on the way. Every year, doctors order as many as 40 million medical imaging scans that require a radioactive isotope called technetium-99m (Tc-99m).

Naslov Germanium (32 Ge) has five naturally occurring isotopes, 70 Ge, 72 Ge, 73 Ge, 74 Ge, and 76 Ge. Of these, 76 Ge is very slightly radioactive, decaying by double beta decay with a half-life of 1.78 × 10 21 years (130 billion times the age of the universe).

The strong variation in energy of the first excited 0+ state in the even-even Ge isotopes is investigated with pairing type interactions in various model spaces. Although it had been possible in previous work to describe this variation in a BCSrandom-phase-approximation (RPA) calculation in the neutron configuration only, the corresponding exact diagonalization disagrees with the BCS-RPA
Jan Makela, general manager of core imaging for GE Healthcare, and his team went out to the industry to find another source of Mo-99 that could help break through the bottleneck. Σ (Ge-68) 0.95 - 1.20 : 1.52 . 5 [1] X-ray Kα: Σ (Ga-68) 8.61 - 8.64 : 4.09 .

It’s a fully automated, positron-emitting cyclotron capable of producing the isotopes needed to cover 99 percent of all clinical PET procedures. In addition, it can run …
Two recent studies have shown that Ge isotopes behave similarly to Si during weathering, with fluids enriched (δ74Ge=0.9 to 5.5‰; Baronas et al., 2018) and weathered solids depleted in heavy isotopes (δ74Ge=−0.1 to 0.6‰; Qi et al., 2019) relative to primary igneous silicates (δ74Ge=0.4 to 0.8‰; Rouxel & …

Energy levels of the low lying states of these nuclei were produced, the electric quadruple reduced transition probabilities B(E2) were calculated as well.
An atom that has different number of neutrons but the same number of protons. While most properties are based on the number of protons in an element, isotopes can have subtle changes between them, including temperature fractionation and radioactivity. innoGUARD Isotope har utöver den motviktsbalanserade vertikala frontluckan även en horisontellt skjutbar blyinfattad lucka med infällt blyglas. Blyglasluckan är upphängd i ett flertal kullagrade hjul i både vertikal och horisontal led för att ge högsta möjliga prestanda.
