How radioactive is barium 133?

Isotopes of barium

Isotope Decay
abundance product
132Ba 0.10% stable
133Ba syn 133Cs
134Ba 2.42% stable

What type of radiation does Barium 133 emit?

Gamma Rays
Gamma Rays Gamma rays originate from the nucleus. 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.

What is barium 133 used for?

Available in millicurie quantities, Ba-133 is used for a variety of purposes, including as an x-ray radiocontrast agent and as a gamma source in multiphase flow meters used in the oil and gas industry.

What is the half-life of barium 137?

approximately 153 seconds
The half-life of Barium-137m is approximately 153 seconds.

What is Barium 133 used for?

The characteristics of Ba-133 make it useful as a dose calibration source for medical isotopes such as iodine-131 used in heart and thyroid diagnostics. Off-shore oil and gas platforms utilize Ba-133 sources in multiphase flow meters to monitor and control pipe flow of oil, gas, and water during production.
