What is the half-life of BA 140?
12.8 days
BARIUM-140, one of the γ-ray emitting isotopes in fallout, has a physical half-life of 12.8 days.
What type of radiation does barium 133 emit?
gamma ray
X-rays X-rays originate from electron orbits. Ba-133 and Co-57 decay when an electron is absorbed into the nucleus increasing the number of protons. To re- balance the energy, a gamma ray is emitted.
How many stable isotopes does BA have?
six stable isotopes
Naturally occurring barium is a mixture of six stable isotopes: barium-138 (71.7 percent), barium-137 (11.2 percent), barium-136 (7.8 percent), barium-135 (6.6 percent), barium-134 (2.4 percent), and barium-132 (0.10 percent).
How many electrons does barium 133 have?
Barium atoms have 56 electrons and the electronic shell structure is [2, 8, 18, 18, 8, 2] with Atomic Term Symbol (Quantum Numbers) 1S0.
What are the two most common isotopes of barium?
Naturally occurring barium is a mixture of six stable isotopes: barium-138 (71.7 percent), barium-137 (11.2 percent), barium-136 (7.8 percent), barium-135 (6.6 percent), barium-134 (2.4 percent), and barium-132 (0.10 percent).
What is the electron configuration of 133 BA?
1 Decay Scheme 133 Ba disintegrates by electron capture mainly to two 133 Cs excited levels of 437 keV (85.4%) and of 383 keV (14.5%) with three very minor branches to the 160 keV, 81 keV excited levels and the ground state.
What is the decay of 56 BA?
Naturally occurring barium ( 56 Ba) is a mix of six stable isotopes and one very long-lived radioactive primordial isotope, barium-130, identified as being unstable by geochemical means (from analysis of the presence of its daughter xenon-130 in rocks) in 2001. This nuclide decays by double- electron capture…
What is the half-life of 130 BA?
There are a total of thirty-three known radioisotopes in addition to 130 Ba. The longest-lived of these is 133 Ba, which has a half-life of 10.51 years. All other radioisotopes have half-lives shorter than two weeks.
How long does it take for barium to decay?
Isotopes of barium. The only notable exceptions are 133 Ba, which has a half-life of 10.51 years, 131 Ba (11.5 days), and 137m Ba (2.55 minutes), which is the decay product of 137Cs (30.17 years, and a common fission product ).
