Comparative analysis of vver-s reactor poly-sell physical parameters with different accident tolerant fuel loads

GammaPix™ is a smartphone application available for both Android and iPhone operating systems that uses the smartphone camera sensor to detect and measure ionizing radiation fields.
Geiger Counter, with Geiger-Mueller (GM) Tube or Probe—A GM tube is a gas-filled device that, when a high voltage is applied, creates an electrical pulse when radiation interacts with the wall or gas in the tube. These pulses are converted to a reading on the instrument meter.
A Geiger counter — named after Hans Geiger, a German scientist from the early 1900s who worked on detecting radiation — is an instrument that can detect radiation.
Can you feel radiation exposure?
(some symptoms may occur as low as 20 Gy or 2000 rads)
Symptoms are extreme nervousness and confusion; severe nausea, vomiting, and watery diarrhea; loss of consciousness; and burning sensations of the skin. Onset occurs within minutes of exposure. Stage lasts for minutes to hours.
In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. Microwaves (like the ones used in microwave ovens) are a subsection of the radio wave segment of the EM spectrum.
Gamma waves can be stopped by a thick or dense enough layer material, with high atomic number materials such as lead or depleted uranium being the most effective form of shielding.
Using the above principle, fast neutrons can be detected in any organic (plastic or liquid) scintillator. The efficiency of neutron absorption in a liquid scintillator can be increased by adding 0.5% by weight of Gadolinium to the liquid.
