  • Most of the radiation hazard from nuclear bursts comes from short-lived radionuclides external to the body; these are generally confined to the locality downwind of the weapon burst point. This radiation hazard comes from radioactive fission fragments with half-lives of seconds to a few months, and from soil and other materials in the vicinity of the burst made radioactive by the intense neutron flux.
  • Bullets could vaporize a brick story building. I'm not 100% sure about that, but that's what the report said. Radioactive substances are unstable and must decay and then becomes stable. This process produces lots of heat so the Soviets had to refrigerate their nuclear bullets at all times and use special vehicles to transport them.
  • Even if a disastrous meltdown never occurred, a small portion of radioactivity must be released from reactors. This radioactivity enters the human body through breathing and the food chain, as gases and tiny metal particles. They kill and injure healthy cells, leading to cancer, and are especially harmful to the fetus, infant, and child…

  • Jun 23, 2020 · The Elephant’s Foot—a “monster” that spreads death even today is hidden in the bowels of Chernobyl. It is a mass of about 200 tons of molten nuclear fuel and rubbish that was burned and shaped into a shape reminiscent of an “elephant’s foot.” This mass remains radioactive and scientists cannot reach it. Chernobyl, the name of a town in the then Soviet Union or the present Ukraine ...
  • Iodine-131 is a major concern in any kind of radiation release from a nuclear accident because it is volatile and because it is highly radioactive, having an 8 day half-life. It is of further concern in the human body because iodine is quickly swept up by the thyroid, so that the total intake of iodine becomes concentrated there.

  • If nuclear radiation damages the ability of the cell to repair DNA, the cell can. Retreat to an irreversible state of dormancy (known as senescence); Commit suicide (known as programmed cell death); or; Progress into unregulated cell division, possibly leading to tumors and cancers. Nuclear radiation can harm the human body is many other ways as well.

  • The most common is the uranium-238 decay series, which produces lead-206 in a series of 14 sequential alpha- and beta-decay reactions (Figure 20.5 "A Radioactive Decay Series"). Although a radioactive decay series can be written for almost any isotope with Z > 85, only two others occur naturally: the decay of uranium-235 to lead-207 (in 11 ...

  • The human fetus, infants, and young children--whose cells are multiplying most frequently--are thus the most sensitive to radiation damage; blood-forming organs such as the bone marrow are also particularly vulnerable. Radiation can also damage the body's immune system and cause a general degeneration in the health of the cell structures.

  • Beta decay is a nuclear decay process where an unstable nucleus transmutes and ejects particles to become more stable. There are two different types of beta decay - beta minus and beta plus. In both of these decays, a nucleon in the nucleus is transformed into a different type of nucleon, releasing particles in the process. Both beta minus and ...

The first gamma ray source to be discovered historically was the radioactive decay process called gamma decay. In this type of decay, an excited nucleus emits a gamma ray almost immediately upon formation (it is now understood that a nuclear isomeric transition, however, can produce inhibited gamma decay with a measurable and much longer half-life).

Nuclear reactions do indeed arise in the human frame, however, the frame does no longer use them. Nuclear reactions can lead to chemical damage, which the body may be aware and try and restoration. There are three predominant types of nuclear reactions: Nuclear fusion: this is the joining of small atomic nuclei into one nucleus.

The most serious biological damage results when these radioactive emissions fragment or ionize molecules. For example, alpha and beta particles emitted from nuclear decay reactions possess much higher energies than ordinary chemical bond energies. Nuclear medicine uses small amounts of radiation to provide information about a person's body and the functioning of specific organs, ongoing biological processes, or the disease state of a specific illness. In most cases the information is used by physicians to make an accurate diagnosis.

  • Radiation from radon and its radioactive decay products consists of mainly alpha particles, which have very limited ability to penetrate tissue but can damage cellular DNA in the lung if the radioactive source is inhaled and deposited in the airways. Gamma rays and X-rays, in contrast, are highly penetrating and can affect cells even when the radiation source is outside the body.
