What form of ionizing radiation causes radiodermatitis?
alpha
What does the lonizing radiation sign mean?
Radiation is typically emitted from an energy source. Ionizing radiation means that the radiation has enough energy to bond to an atom. This causes the atom to become charged.
What is the result of large doses of ionizing radiation that causes good and bad effect to plants and animals?
Ionizing radiation is any kind of radiation with enough energy (enough energy = wavelength is sufficiently short) to release a valence electron from a molecule. For instance, gamma rays emitted by the sun are highly energetic EM waves that are considered to be ionizing. A molecule that has had one of its valence electrons stripped is in a higher energetic state called a radical. When a biological entity encounters ionizing radiation, it forms radical molecules. These are often in the singlet and triplet excited states. The triplet excited state is highly reactive, and wreaks havoc on biological systems by reacting and altering the structure of DNA, proteins, and other biomolecules. Ionizing radiation typically does not have any "good" effects on plants or animals.
When is radiant energy harmful?
The danger of radiation, specially ionizing radiation, is the capacity to harm the genetic material. Ionizing radiation can break double the strand of DNA and inactivate vital genes necessary for living or health of the organism. Depending upon the intensity of the radiation, the cell can undergo death (e.g., apoptosis or programmed cell death) or to carry a genetic defect that is inherited to the next generation.
What are the best ways to protect against the effects of exposure to radiation?
Ionizing radiation is "stopped" by passing the radiation through matter which becomes ionized. By definition, ionizing radiation will ionize material that it passes through. Ionization involves transferring energy, so the entity doing the ionizing loses energy. That is the simple answer. A closer look reveals greater complexity. One needs to be clear about language to be accurate in the question and answer. Normally when referring to ionizing radiation, one is referring to high energy particles that are causing the radiation. Normally, when we say such radiation is "stopped" we mean it is diminished to that the harmful effects are insignificant. One does not "stop" such radiation but rather one causes it to lose energy. There will always be a few stray particles with high energy even after the vast majority have lost so much energy that ionization has stopped occurring. If one wants to "stop" ionizing radiation, then creating a large enough (thick enough) barrier will effectively reduce the radiation to insignificance. Of course, depending on the nature of the radiation, some materials may be more effective than others in removing the energy from the radiation. Though ionization, i.e. exicting or removing electrons of atoms, is an important energy loss process, there are also processes that involve the interaction of the ionizing radiation with the nuclei of the material through which it passes. Bremsstrahlung is one such process and so is simple transfer of kinetic energy from the incident particle to the particle in the material. These kinds of processes are larger or smaller depending on the mass and energy of the "ionizing radiation" and so an effective discussion of how well a material can "stop" ionizing radiation depends on the ionizing radiation itself.
What form of ionizing radiation in high doses causes delayed irreversible changes of the skin?
All ionizing radiation in high doses causes irreversible changes to the skin...In some cases the change is caused by death. Say, for instance, that you were exposed to Alpha radiation, it would not penetrate deeply enough to pass through the dead skin cells. If you ingest an Alpha emitter, it could have lethal effects. Beta is perhaps the most dangerous. It penetrates deeply and causes damage to the DNA that can be expected to lead to skin and other cancers. On the other hand, Beta radiation is used to destroy tumors. Gamma radiation, same as X-rays, causes damage that, like Beta, is not limited to the skin. It has been said that there is no safe dose of radiation.
What form of ionizing radiation causes radiodermatitis?
alpha
What type of ionizing radiation causes radio dermatitis?
alpha
The initial effect of ionizing radiation on a cell is that it causes?
The formation of highly reactive ions
Is ordinary light classify as ionizing radiation?
NO, because ordinary light is just giving simple emission of light. Ionizing radiation gives tremendous emission of light it causes cancer. Therefore, if ordinary light like fluorescent lamp which we always use is classified as ionizing radiation, we people have a cancer.....
What is a teratogen example of radiation?
A teratogen is an environmental factor that causes birth defects during prenatal development. An example of a teratogen is ionizing radiation.
What does the lonizing radiation sign mean?
Radiation is typically emitted from an energy source. Ionizing radiation means that the radiation has enough energy to bond to an atom. This causes the atom to become charged.
What is nonionizing radiation?
Ionizing radiation causes some of the atoms it strikes to be ionized. There are several different types: alpha particles, beta particles, neutrons, gamma rays, x-rays, and ultraviolet light. Non-ionizing radiation, which does not ionize atoms, includes visible light, infrared light, radio waves, and so on.To understand the biological effects of radiation we must first understand the difference between ionizing radiation and non-ionizing radiation. In general, two things can happen when radiation is absorbed by matter: excitation or ionization.Excitation occurs when the radiation excites the motion of the atoms or molecules, or excites an electron from an occupied orbital into an empty, higher-energy orbital.Ionization occurs when the radiation carries enough energy to remove an electron from an atom or molecule.Because living tissue is 70-90% water by weight, the dividing line between radiation that excites electrons and radiation that forms ions is often assumed to be equal to the ionization of water: 1216 kJ/mol. Radiation that carries less energy can only excite the water molecule. It is therefore called non-ionizing radiation. Radiation that carries more energy than 1216 kJ/mol can remove an electron from a water molecule, and is therefore called ionizing radiation.Related links are provided below.
