In general, isotopes for SPECT imaging are more easily attainable, and SPECT is generally more widely available than PET.
Based on the general isotope-balance model, the relative proportions of sulfate oxygen derived from water and air were calculated.
All copernicium isotopes are extremely unstable and radioactive; in general, heavier isotopes are more stable than the lighter.
All meitnerium isotopes are extremely unstable and radioactive; in general, heavier isotopes are more stable than the lighter.
In general, the lighter isotope is preferentially incorporated into reaction products while the heavier isotope preferentially remains in the reactant.
In general, the hydrogen isotope ratio of produced CH4 is related solely to that of H2O (e.g., Daniels et al. 1980).
All darmstadtium isotopes are extremely unstable and radioactive; in general, the heavier isotopes are more stable than the lighter.
All roentgenium isotopes are extremely unstable and radioactive; in general, the heavier isotopes are more stable than the lighter.
The accepted leakage rate is ≤ 10−4 mbr.L/s, according to the approved safety report related to iodine-131 production in the TRIGA Mark II research reactor (TRIGA: Training, Research, Isotopes, General Atomics).
Although the known isotopes of ununpentium do not actually have enough neutrons to be on the island of stability, they can be seen to approach the island as in general, the heavier isotopes are the longer-lived ones.
While the known isotopes of livermorium do not actually have enough neutrons to be on the island of stability, they can be seen to approach the island as in general, the heavier isotopes are the longer-lived ones.
