The WC-135 Constant Phoenix is a special-purpose aircraft derived from the Boeing C-135 Stratolifter and used by the United States Air Force. Its mission is to collect samples from the atmosphere for the purpose of detecting and identifying nuclear explosions .
Iodine-135 is an isotope of iodine with a half-life of 6.6 hours. It is an important isotope from the viewpoint of nuclear reactor physics . It is produced in relatively large amounts as a fission product , and decays to xenon-135 , which is a nuclear poison with the largest known thermal neutron cross section , which is a cause of multiple ...
Xenon-135 (135 Xe) is an unstable isotope of xenon with a half-life of about 9.2 hours. 135 Xe is a fission product of uranium and it is the most powerful known neutron -absorbing nuclear poison (2 million barns ; [ 1 ] up to 3 million barns [ 1 ] under reactor conditions [ 2 ] ), with a significant effect on nuclear reactor operation.
One radian is defined as the angle at the center of a circle in a plane that subtends an arc whose length equals the radius of the circle. [6] More generally, the magnitude in radians of a subtended angle is equal to the ratio of the arc length to the radius of the circle; that is, =, where θ is the magnitude in radians of the subtended angle, s is arc length, and r is radius.
Rad, Ostas' 40-year-old nephew, also admitted he had hit the victim "with my hands," in the presence of the two women and his uncle. "I saw a lot of violence. It was a shock for me too. I thought ...
The rad is a unit of absorbed radiation dose, defined as 1 rad = 0.01 Gy = 0.01 J/kg. [1] It was originally defined in CGS units in 1953 as the dose causing 100 ergs of energy to be absorbed by one gram of matter. The material absorbing the radiation can be human tissue, air, water, or any other substance.
The yield of 135 Xe for uranium fission is 6.3%; about 95% of 135 Xe originates from decay of 135 I. 135 Xe is the most powerful known neutron absorber , with a cross section for thermal neutrons of 2.6×10 6 barns , [ 1 ] so it acts as a " poison " that can slow or stop the chain reaction after a period of operation.
But acting ICE Director Tae Johnson told lawmakers during an April 2023 budget hearing that deportation flights cost $17,000 per flight hour for 135 deportees and typically lasted five hours.
