What is inizing radiation?
An ionizing radiation is a radiation that is strong enough (energetic enough) to produce ions, that is, to separate electrons from an atom (thus leaving behind a charged atom, known as an ion)
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.
On the atomic level what causes an electromagnetic wave to be emitted?
On any level the movement of charge carriers (electrons, protons etc) cause EM radiation to be emitted. Gamma rays are also emitted as the result of some radioactive decay reactions All radioactive decay reactions produce EM radiation of some kind because they involve the movement of charge carriers such as the ejection of alpha particles (double positive charge).
What occurs inside a Geiger counter when ionizing radiation strikes it?
Geiger counters have gas in them that does not normally conduct electricity. When ionizing radiation passes into a Geiger counter, it makes the gas conductive, and the conductivity can be measured, indicating that the radiation is present. Gamma rays, which have no charge, can be measured by interacting with lead or steel in a Geiger counter, putting electrons into the gas.
How do radiation produce?
How do radiations produce heat?
What kind of radiation that can produce charged particles from atoms or molecules it strikes?
ionizing
What types of ionizing radiation produce the least amount of scatter radiation?
All of the ones on the list provided with the question have pretty much the same characteristics.

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 two kinds of luminescence can minerals produce?
The two main types of mineral luminescence are photoluminescence and cathodoluminescence. The excitation sources are ultraviolet radiation and electrons, respectively. Other types are ionoluminescence, chemiluminescence and others. - See the related link below.

Cancer and related diseases are caused due to primary radiation or secondary radiation or non ionization radiation or ionization radiation?
Cancers are caused by uncontrolled growth of tissue. Most commonly caused by environmental chemicals. Or fine fibres such as Asbestos or very fine glass. Ionizing radiation can cause cancers IF the damage it does then goes on to produce an unwanted growth of tissue.
What are measurements of radioactivity referred to as?
Roentgen:A unit of radiation exposure equal to the quantity of ionizing radiation that will produce one electrostatic unit of electricity in one cubic centimeter of dry air at 0°C and standard atmospheric pressure.[After Wilhelm Konrad Roentgen.]

How does radiation affect the structure of a stable molecule such as a molecule of water?
Radiation can involve gamma rays, X-Rays, alpha particles and beta partcles. In terms of molecules these are termed ionizing radiation but they both ionize and break bonds to produce radicals. Ionizing radiations effect on water is to produce hydrogen peroxide, hydrogen, oxygen, ozone, . The pathways are complex involving the breakdown of water molecules into positively charged radicals, such as H2O+, neutral radicals OH and H and solvated electrons. Chain reactions coupled with reionization of some of the "initial" products makes for a complex situation.

What are the Application of radiation in food and agriculture?
one of the application of radiation to food is that,it delays the fruit ripening and it also help prevent the growth of microoganism...in agriculture ,the usage of tracer allows scientist to optimize the use of fertilizing chemical...the ionizing radiation from radioisotope was used to produce crops that are disease resistant.....it also creates crops with a shorter growing time,that help the farmer to reduce their expenses....
