How does ionizing radiation works for sterilixe insects?
Ionizing radiation is a method of area wide pest control management. Ionizing radiation works by making insects unable to reproduce (sterile). Gamma radiation is most often used for this task, though sometimes high energy electrons or X-rays are used.
What are the dangers of neutron radiation?
Neutron radiation is as dangerous as any other ionizing radiation, if not more dangerous,as by some sources, it can be as many as ten times more dangerous as other ionizing radiation. It is not directly ionizing radiation, since neutrons do not hold electric charge, but they interact (collide) with nuclei in it's path, creating isotopes, most of the time non-sable, radioactive isotopes. That is why neutron radiation induces a secondary radiation in the material it passes through. The penetration of neutron flux is rather strong, and is not affected by the shield density, as is the case with gamma radiation, but rather by a material rich with Hydrogen (deuterium) atoms, since H atoms contain one single proton/neutron, and the collision physics slow down the neutrons in this matter most efficiently. Therefore, heavy water, plexiglass, plastics and similar materials are used as an effective shield in neutron radiation protection.
Why is radioactivity referred to as ionizing radiation?
Radioactivity occurs with the breakdown r decay of certain unstable atomic nuclei. This nuclear radiation is dangerous because it has a lot of energy-on the order of millions of electron volts per emitted particle. Because chemical bonds take about 3-4 electron volts to break, this energy is enough to break apart ordinarily stable molecules into smaller, highly reactive fragments-most of which are ions. Thus, nuclear radiation gets the name ionizing radiation.
What type of radiation causes most ionisation?
The electromagnetic radiation most capable of ionizing is the radiation with the highest energy per quantum. That in turn implies the radiation with the highest frequency (shortest wavelength). The highest-energy end of the electromagnetic spectrum is the region we call "gamma rays". We can't generate these, and the gamma rays we observe all originate in radioactive nuclear processes.
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.
Which type of radiation is most likely to damage DNA ionizing or nonionizing?
Ionizing
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 is the most common mutagen?
Ionizing radiation is the most common form of mutagen.

What material is most resistant to the penetration of ionizing radiation?
For example lead, uranium, composites with boron.
How does radioactivity spread cancer?
There is no doubt that ionizing radiation can and does cause cancer in humans. Radioactive atoms produce ionizing radiation when they decay and most carcinogens contain some radioactive atoms. This paper presents the case that many cancers are ultimately caused by the ionizing radiation resulting from radioactive decay. This proposition is supported by the observation that the histology of cancers known to be caused by radiation are indistinguishable from the histology of cancers currently not considered to be related to radiation.
What penetrates the earth's atmosphere to reach the surface?
Electromagnetic radiation from the sun, most in the form of visible light.

What kind of particles are equivalent to helium nuclei and are the most ionizing form of nuclear radiation?
An alpha particle
Which of the following cell types are at least sensitive to ionizing radiation damage?
Cells that are actively dividing are most sensitive to radiation damage.
How radiation from the sun penetrates the atmosphere by heating the air?
Solar radiation penetrates most of the atmosphere and is mostly absorbed by earth's surface. The surface then radiates energy of a different wavelength (in the thermal infrared part of the spectrum, which we perceive as heat) back to the atmosphere, heating the lower atmosphere.
What is the result and effect of rhamphant bombing?
Most damage comes from the explosive blast and then thermal radiation, prompt ionizing radiation are produced and cause significant destruction within seconds or minutes of a nuclear detonation.
