various types of radiation relevant to particular disciplines, including X-rays and beta particles.
Different
types of radiation equipment and scheduled of radiation therapy used, and limited numbers of patients in studies make interpretation difficult.

types of radiation from what one encounters in space, and at best the correlation of data is imprecise.

type of radiation treatment that conforms to the shape of the tumor.
In January 2012, Christoph Weniger, a physicist at the University of Amsterdam in the Netherlands, started noticing hints of a
strange type of radiation around the center of our galaxy.
Based on previous research, the researchers hypothesized that radiation from phones would accelerate progression of the disease because other
types of radiation cause free radical damage.
With only one tight pair known, he says, it was difficult to assess how common even tighter black hole pairs are, which are crucial in the hunt for gravitational waves — a
subtle type of radiation predicted by Einstein's general theory of relativity.
If deemed necessary, countermeasures for immunity could include new
types of radiation shielding, nutritional supplementation, pharmaceuticals and more.
University of Chicago radiation oncologists were the first in the Chicago area to offer this advanced
type of radiation therapy.
Himalayan salt lamps are attributed to purifying the air by releasing negative ions into the atmosphere that neutralize the positive ions emitted from
different types of radiation (like from cell phones and computers).
Male rats developed heart tumors when exposed to high levels of
a type of radiation used by the wireless telephone industry, according to the draft studies released Friday.
The main concern people have about cell phones is that they emit radio - frequency (RF) energy,
a type of radiation.
While pregnant women can't avoid
all types of radiation, it's best to limit any unnecessary exposure.
Radiation therapy may also require an interruption in breastfeeding, depending on
the type of radiation used and the duration of treatment.
Overall, about one - third of men with prostate cancer receive
some type of radiation therapy.
Brachytherapy is
a type of radiation therapy (RT) where radioactive seed implants are inserted directly into a patient's tissue to deliver treatment to the tumor while limiting radiation exposure for surrounding tissue.
Fission fragments are typically radioactive, and can emit different
types of radiation, among them neutrons.
Gregg Hallinan of the California Institute of Technology and colleagues have detected
both types of radiation from what appears to be a brown dwarf, an object that straddles the boundary between planet and star.
That's because different nuclear materials give off their own specific blend of gamma rays, X-rays and so on, and
each type of radiation penetrates insulators with different strengths.
And for some frequencies of light — such as terahertz radiation,
a type of radiation that falls between the infrared and microwave bands of the electromagnetic spectrum and passes through many materials that block visual and infrared light — ordinary materials developed so far don't work as lenses at all.
The big corrections are dose rate,
type of radiation, and the differences between the populations who are exposed.
A new microscopic laser uses a sandwich of semiconductors to generate a beam of t - rays, a rarely used — but much coveted —
type of radiation.
Delp and his colleagues also exposed mice to
the type of radiation that Apollo astronauts would have experienced.
The final group was exposed to
both types of radiation, plus the vacuum.
The doctor explained that there are two
types of radiation: ionizing and non-ionizing.
To reach this level, it is necessary to know how a dosimeter will respond to different
types of radiation and the optimal conditions for usage.
Scan from the region of visible light towards the longer wavelengths of the electromagnetic spectrum and you'll find, sandwiched between microwaves and the infrared,
a type of radiation that we have previously had little time for: terahertz rays, or T - rays.
The high - energy particles,
a type of radiation, vary over time and altitude and pose a health risk to exposed space travelers.
Even what we refer to as the heat given off by radiators is
a type of radiation — infrared rays.
CyberKnife, as well as other types of advanced radiation treatment devices (such as image guided Linac [Linear Accelerators] and Tomotherapy), are used in
a type of radiation therapy called stereotactic radiotherapy, also known as stereotactic body radiotherapy or SBRT.
cosmic microwave background
A type of radiation that fills the universe with a faint glow.
Some types of radiation seem to be dimly emitted not from a certain object, but from the overall universe.
X-rays and gamma rays are two other
types of radiation — both of which are found naturally and in man - made devices like imaging tests, scanners, and certain power plants — that can cause DNA mutations, which may lead to cancer in the future.
The limited evidences in humans may be why regulators are claiming that
this type of radiation is safe.
