Explain how radiation damage in a steel pressure vessel differs when caused by neutrons and gamma rays, respectively.
Gama rays cause damage but very few atomic displacements. The damages can include production of lattice defecta in that do not undergo , formation of gas bubble, potential for enhanced leaching. It can also effect the density and chemical durability.
Neutron radiation significantly increases the yield and tensile strength and decreasing the ductility. Also there is an increase in hardness and thereby cause atructural damage to the crystal lattice.

The oxygen Enhancement Ratio would be greater with what type of radiation? Gamma Rays Neutrons Neutrinos Alpha Particles
Most of the damage to DNA caused by x-rays occurs when they interact with water, knocking one of the electrons loose and creating a free radical. The energy required to do this is approximately 300 kJ/mole. If a stray photon is moving at the speed of light, estimate the wavelength(s) of electromagnetic radiation needed to create a free radical.
Gamma-rays (Y-rays) are highly energetic electromagnetic radiation that are emitted when the nuclei undergo transitions in the energy levels. The energy of the y-rays is upward of 100 keV. Due to the high energy, the rays are not appreciably absorbed by even several centimeters of materials such as concrete or wood. However, dense metals such lead, are effective Y-ray absorbers. The amount y-rays that are absorbed depends on the material and the energy of the gamma-rays, the higher the energy,...
A person is most likely to experience serious tissue damage when exposed to which of the following forms of electromagnetic radiation? ultraviolet gamma rays radio waves microwaves Use the Heisenberg uncertainty principle to calculate the uncertainty (in meters) in the position of a honeybee weighing 0.78 gg and traveling at a velocity of 0.86 m/sm/s . Assume that the uncertainty in the velocity is 0.1 m/sm/s. Express your answer in meters to one significant figure. What is the number of...
please explain these three things : 1.) a protooncogene and it’s function and how it differs from a normal version of the gene when it’s cancerous 2.) why so many cancer cells duplicate uncontrollably vs normal cells and why normal cells only divide 20 times 3.) how dna turns into pre rna and then mrna , and draw an example
