 Delta ray - Wikipedia, the free encyclopedia
Delta rays appear as branches in the main track of a cloud chamber.
Otherwise called a knock-on electron, the word Delta Ray is also used in high energy physics to describe single electrons in particle accelerators that are exhibiting characteristic deceleration.
In science fiction, a "delta ray" is often used to describe an undefined, fictional type of ray or radiation, sometimes as a hazard, sometimes used in energy weapons.

 Gamma ray Summary
Gamma rays, such as those emitted from the unstable nuclei of cobalt-60 and cesium-137, are used in industry to assess the metallurgical integrity of, for example, pipes, girders, and turbine blades.
Gamma rays with energy close to a resonance energy, however, may also be absorbed and emitted, leading to a peak with nonzero width in the measured spectrum.
Gamma rays are emitted by cosmic sources or by radioactive decay of atomic nuclei which occurs during nuclear reactions or the detonation of nuclear weapons.

If the rays must be perfectly simmetrical, the first ray is supposed to have 0.5 as X component and the last ray must have -0.5 as X component.
Generating rays by simple addition would probably be a case of linear interpolation of each of the three component vectors, for both across and down the set of rays.
If delta is 60/320 then both give the correct answer, as 60/320 has a perfect floating point representation.

 Spaceflight Now | Breaking News | Origin of cosmic rays revealed with gamma rays
Gamma rays are the most penetrating form of radiation we know, around a billion times more energetic than the X-rays produced by a hospital X-ray machine.
However, luckily for life on Earth, gamma rays from objects in outer space are stopped by the atmosphere; when this happens, a faint flash of blue light is produced, lasting for a few billionths of a second.
The telescopes, known as Cherenkov telescopes, image the light created when high-energy cosmic gamma rays are absorbed in the atmosphere, and have opened a new energy domain for astronomy.

Unnecessary submission of x-rays can be costly and time-consuming for the dental office, and may actually delay processing of your claim.
On occasion, a dental consultant may deem it necessary, given the circumstances of a particular case, to request x-rays for procedures that are not on this list.

 Solar - Heating Panels for Canada Geese
The birds are dropping their wings by their sides to expose the dark rump feathers, and catch a bit of warmth from the spring sun.
Since birds don’t pant like a dog or sweat like a human to cool down, heat generated during strenuous activities like long migrations, is dispensed through the backside of the flying bird, kind of like a natural cooling system.
Similarly, when the weather turns cold and the bird is inactive, it can take in a few rays to help warm- up by exposing their custom- made solar heating panels in this area to a little spring sunshine.

 Beta particle Summary
Beta rays are more easily deflected than are alpha rays and were, therefore, studied first.
Since Joseph J. Thomson had demonstrated in 1897 that cathode rays are a stream of electrons, the identity of the beta rays was also apparent.
Beta rays pose relatively little health hazard, therefore, unless they are ingested into the body.

When the rays "go through matter—it can be a rock, a body, or your brain—they have so much energy and charge that they produce a kind of hole.
In the case of galactic cosmic rays, the dragons may be all too real: metaphorically fire breathing, ineluctable, lethal.

One contribution is the variation in the number and energy of delta rays produced as electrons travel thru the crystal.
In this treatment the total light emitted per unit path length of the incident particle is the sum of two contributions: one from the highly ionized primary column, and one from those delta rays which escape the primary column and produce light with a high efficiency.
After subtracting the contributions to resolution due to non-proportionality of electron response and to delta rays, a residual resolution is left which consists of an energy dependent term and an energy independent term.

This is translated into the radial distribution of probability for the activation of a target through application of the response to gamma rays.
Once our parameters are measured from a few irradiations with gamma rays and heavy ions, we are able to calculate response for arbitrary heavy ion bombardment, even to "thindown", and for mixed radiation fields.
Perhaps it is because the response of each detector to both gamma rays and heavy ions is attributed to secondary electrons, because the response to heavy ions is calibrated by the response to gamma rays, and because the model is mechanistic only in regard to the physics of radial dose production by delta rays.
