EPA administrator Lee Zeldin talks the future of nuclear
In a recent interview on New York radio station 77 WABC, administrator of the Environmental Protection Agency Lee Zeldin talked with host John Catsimatidis about the near-term future of the domestic nuclear industry and the role the EPA will play in the sector.
Catsimatidis kicked off the interview by asking if the U.S. will be able to reach total energy independence. Zeldin responded by saying that decreasing energy dependence on other countries, especially adversaries, was a top priority for him and the Trump administration.

Gamma rays from the fission product nuclides 140Ba and 140La are frequently used for monitoring fission rates in neutron activation detectors consisting of fissionable materials. Systematic errors that can occur when the 1596-keV line of 140La is taken as the monitor line can be avoided by using the 537-keV line of 140Ba. The gamma-ray emission probabilities per decay of 140Ba and 140La were redetermined for the more abundant lines with a relative uncertainty of about ±1% at the 68% confidence level.
