Certain crystals, sodium iodide being an excellent example, emit flashes of visible light when struck by ionizing radiation.
An important quantitative relation between the solubility of a given ionogen in different solvents and the ionizing powers of the solvents, as determined by their dielectric constants (p.
From Walden's work it appears that the dielectric constant finally determines the quantitative ionizing effect of a solvent.
The comparative stability of this basic salt represents an instance of the different ionizing power, or basic strength, of the three hydroxide groups of a trivalent base (see p.
The ionizing power of solvents, as has been explained, is intimately connected with their dielectric properties.
Alcohols have also ionizing power; methyl or wood alcohol, which stands nearest to water, has a higher ionizing power than ordinary ethyl alcohol.
It is evident,[150] from Walden's equation showing the relation between the ionizing power and the dielectric constant of a solvent (p.
The most important ionizingsolvent is water and, of the common solvents which cause ionization, it is the most powerful in this particular.
A careful scrutiny of the group of highly-ionizing solvents (p.
For positive evidence of the ionizing power of light, see Haber, ‹Z.
He was sure the high currency ionized the gas, but he somehow had not got it to ionizing fast enough.
Then, more positively: "I think you undoubtedly are ionizing the vapor.
They have a great ionizing power and a velocity about one-fifteenth that of light.
Ionization of Gases One of these phenomena is the power of forming ions or carriers of electricity by the passage of the rays through a gas, thus ionizing the gas.
They have the least ionizing power and a very great velocity.
Wilson has by instantaneous photography been able to photograph the track of an ionizing ray through air.
They show a strong deflection in magnetic and electric fields, have less ionizing power than the alpha rays, and a velocity of the same order as light.
These bends show where the ionizing ray, in this case an alpha particle, has been deflected by more or less direct collision with an atom.
If the atmosphere at different heights is exposed toionizing radiation of uniform intensity the rate of production of ions per cc.
Let q be the number of ions (positive or negative) produced in one cubic centimetre of the gas per second by the ionizing agent, n1, n2, the number of free positive and negative ions respectively per cubic centimetre of the gas.
We may use equation (1) to determine the rate at which the ions disappear when the ionizing agent is removed.
When the ions are not removed from the gas, they will increase until the number of ions of one sign which combine with ions of the opposite sign in any time is equal to the number produced by the ionizing agent in that time.
In one method air, exposed to some ionizing agent at one end of a long tube, is slowly sucked through the tube and the saturation current measured at different points along the tube.
On this view the Rontgen rays or other ionizing agent acting on the gas between the plates, produces positive and negative ions at a definite rate.
We can easily calculate the number of free ions at any time after the ionizing agent has commenced to act.
Suppose that we expose the gas between two parallel plates A, B to Rontgen rays or some other ionizing agent, then stop the rays and apply a uniform electric field to the region between the plates.
Because of their common mode of action and effects on living organisms, these different kinds of radiations are known collectively as ionizing radiations.
Liquid scintillation solutions share with other scintillating materials the property of converting into visible light the energy deposited in them by ionizing radiation.
All the particles and rays that can leave a detectable track of ions behind are called “ionizing radiation” and these are easy to detect.
This is because so many subatomic particles use up their energy in ionizing atoms, knocking electrons away, and never initiate nuclear reactions at all.
Gamma rays, though they carry no charge, are a wave form capable of ionizing atoms.
If this occurs, the risk of biological damage from the destructive ionizing radiation (see "Radioactivity" note) is multiplied.
The biological effects of all forms of ionizing radiation have been calculated within broad ranges by the National Academy of Sciences.
Ionizing radiation is radiation that can cause damage to biological tissues.
Oak Ridge scientists began to try to find out whether the pipe-organ wasps actually were discriminating against muds containing all or some of these radioisotopes or against the ionizing radiation from them.
Illustration: Checking pine seedlings exposed to ionizing radiation from a radioactive source (on tripod) in a controlled ecosystem.
Millikan's charge carriers were minute oil drops, which were given elementary charges by means of ionizing rays from radium.
With a startled curse the guard thudded to his feet, peered tensely into the darkness, his weapon sending twin milky beams of the powerful ionizing ray toward the source of the sound.
The girl had only to press the trigger and a powerful current would leap along the path of those ionizing beams.
Fourteen percent as nuclear radiation, 4 percent as initial ionizing radiation composed of neutrons and gamma rays emitted within the first minute after detonation, and 10 percent as residual nuclear radiation (fallout).
Nuclear radiation patients fall into three categories: · The irradiated patient is one who has been exposed to ionizing radiation, but is not contaminated.
Physiological Effects of Ionizing Radiation A nuclear burst results in four types of ionizing radiation: neutrons, gamma rays, beta, and alpha radiation.
Physiological Effects of Nuclear Weapons The physiological effects of nuclear weapons are the result of exposure to the blast; thermal radiation; ionizing radiation (initial or residual) effects; or a combination of these.
The former term is not entirely suitable in that it does not define the type of radiation as ionizing and allows possible confusion with other types of radiation (e.
Accordingly, radiation injury is used in this report to mean injury due only to ionizing radiation.
It was concluded that persons exposed to the bombs at the time of detonation did show effects from ionizing radiation and that some of these patients, otherwise uninjured, died.
A molecular ray reached out--and disappeared in flaring ions on a shield utterly impenetrable in the ionizing atmosphere.
Suddenly the energy flared out violently, a terrific burst of energy, ionizing the air in the entire room, and shooting it with tiny, burning sparks.
Their rays, before ionizingthe air brilliantly red, were now dark.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "ionizing" in a variety of sentences. We hope that you will now be able to make sentences using this word.
