Medical Physics often use the isotope 18F, which decays by positron emission. (i) What mechanism competes with positron emission during nuclear decay(it is more important in heavier isotopes than in light isotopes like 18F)? (j) During positron emission, another particle also is ejected from then nucleus. What is this particle?

Let's do a little particle physics. Back in the '9os there was a large electron-positron collider at CERN in Geneva, Switzerland, called the "Large electron-positron collider," or LEP for short. (This collider was broken down and rebuilt into an even larger one that runs to this day, called the "Large hadron collider" or LHC.) It was LEP that discovered the W and Z bosons, which mediate weak nuclear processes like the beta decay of free neutrons Anyway, near...

what is the answer of 12 and
13
estimated as equivalent to that released by 20.000 tons of TNT. Assume 200 MeV is released when a 235 U nucleus absorbs a neutron and fission that 3.8 x 10' J is relensed during detonation of 1 ton of TNT. nuclear fissions occurred at Hiroshima, and what was the total de mass? utron and fissions and of 1 ton of TNT. How many was the total decrease in Scanned by CamScann 1.9...

Technetium Dosage. Radioactive isotopes are often used for medical imaging. Technetium-99m (Tc-99m) is a particularly popular isotope since it has a short half-life and is easy to make. Also, Tc-99m can be chemically bonded to a number of different compounds and cell types for imaging different parts of the body. Tc-99m has a half-life of 6.02 hours. It decays into Tc-99 by emitting a gamma ray of energy 140 keV. For this problem, assume that Tc-99m is present in the...
