Launched in April 1996, it has made an important contribution toward solving one of astronomy s greatest enigmas by detecting for the first time X ray emission from the source producing a gamma ray burst, thus allowing astronomers worldwide to watch the fading visible light counterpart of the gamma ray burst.

Integral (International Gamma ray Astrophysical Laboratory) to observe and analyse cosmic gamma ray sources

This equipment uses two types of rays x rays and gamma rays to detect objects such as weapons, bombs and other explosives, and drugs.

(e) In the International Gamma Ray Astrophysics Laboratory (INTEGRAL) project devoted to measuring the X ray and gamma ray deep space sources

Within this band are gamma ray pulsars and other unidentified sources of gamma rays.

Relatedly, the CGRO apos s Energetic Gamma Ray Experiment Telescope (EGRET) provided the first detailed all sky map of highly energetic gamma ray objects, pointing out several different types of gamma ray sources.

This is a gamma radiation spec scan that uses gamma radiation to map three dimensional function within the brain.

New sources emitting radiation in the annihilation gamma line of positrons have also been discovered.

This applies to such techniques as gamma ray spectroscopy, passive gamma imaging and neutron multiplicity analysis.

For the first time sources emitting radiation in the annihilation gamma line of positronium have been localized.

For the first time, sources emitting radiation in the annihilation gamma line of positronium have been localized.

Astronomers analyzing EGRET apos s data have also identified what they think are massive black holes in the middle of distant galaxies that are sending gamma rays in Earth apos s direction.

Such equipment, which will be supplied to all remaining border posts in the near future, employs two kinds of rays, namely X rays and gamma rays, and seeks such contraband items as arms, bombs, explosives and narcotic drugs.

But the potential advantage was that gamma rays, unlike X rays, are not influenced by breast density.

For most of the infrared and the ultraviolet, X rays and gamma rays, instruments need to be placed just above the atmosphere.

In other developments, scientists analyzing data from the Compton Gamma Ray Observatory (CGRO), which was launched in April 1991, found new evidence that gamma ray bursts extend into the far reaches of the universe and thus bear an imprint of the universe apos s expansion.

Gamma ray

And we're now routinely using one fifth the radiation dose that's used in any other type of gamma technology.

The second is the gamma ray burst experiment, consisting of two scintillation detectors to study celestial gamma ray bursts in the energy range of 20 3,000 kilo electronvolts.

Gamma Ray Missions

The Spectrum X Gamma mission will conduct multiple experiments in a broad wavelength range from ultraviolet through Grays to gamma rays.

Experiments concerning examination of energetic particles and radiation from solar flares, localization of sources of intense transient emissions of gamma ray radiation, monitoring of galactic and extragalactic X ray diffuse background and examination of energetic neutral atoms in radiation belts (in cooperation with Italy) would be conducted on board.

(c) Photo neutron interrogation photo induced neutron emission occurs when the energy of an incoming photon (X ray or gamma ray) is above a certain threshold and atoms of low atomic weight undergo photonuclear reactions that emit neutrons.

Scientists believe, for example, that the interactions of cosmic ray particles with gas between the stars produce diffuse gamma ray emissions from our Milky Way galaxy.

You don't want to get close to gamma rays, it could be dangerous.

Several gamma ray bursts of potential celestial origin have been detected in the energy range of 20 to 3,000 kilo electron volts.

HARTRAO also makes supporting radio observations of objects currently being investigated by the Compton Gamma Ray Observatory.

With TDRS 1 and GRTS, NASA has extended real time data retrieval to the full orbit for GRO, which is studying the evolution of the universe, the nature of puzzling astronomical objects, and the processes that produce very high energy radiation.

The gamma ray burst experiment payload and the retarding potential analyser payload on board SROSS C2 satellite, launched in 1994, continues to provide valuable data to the scientists.

Work is continuing in connection with the solar research programme under the international Coronas I project (research on dynamic, active processes and the properties of solar cosmic radiation and electromagnetic solar radiation in the radio, visible, ultraviolet, X ray and gamma bandwidths).

Turkey is a participant of the x ray astronomy experiment called Spectrum X Gamma, built under the coordination and leadership of the Russian Federation apos s Cosmic Research Institute (IKI), Moscow.

This ESA mission, which is planned for launch in 2001, is a successor to Granat Sigma (launched in 1989) whose most important instrument is the Sigma telescope designed to locate gamma sources (cooperation between the Russian Federation and France).

A solar research programme is being continued under the international Coronas I project (research on dynamic, active solar processes, the properties of solar cosmic radiation and electromagnetic radiation in the radio, visible, ultraviolet, X ray and gamma bands).

On November 29, 1993, NASA repositioned its first Tracking and Data Relay Satellite (TDRS 1), launched in 1983 and already serving beyond its 10 year lifetime, to recover scientific data from the Compton Gamma Ray Observatory (GRO), launched in 1991.

The X ray astronomy payload on board IRS P3 and the gamma ray burst detector and retarding potential analyser on board SROSS (Stretched Rohini Satellite Series) C2 satellite are providing valuable data to the scientists.

We use them to communicate, cook, and diagnose and cure disease. The unified theory of electromagnetism has led to profound advances across all physical science, from atomic physics (where lasers and masers are essential tools) to cosmology (where the microwave background radiation is our window on the Big Bang).

A significant portion of GRO data would otherwise have been lost due to the failure of a tape recorder on the spacecraft.

Under the terms of this programme, France supplied the telescope for the gamma ray study of the sky.

The Russian committee for the international scientific research programme is conducting experiments aboard the European Integral space laboratory for continued observation and study of X ray and gamma radiation from space sources.

SAC B is an Argentine American satellite designed to advance the study of solar physics and astrophysics through the examination of solar flares, gamma ray bursts, diffuse X ray cosmic background, and energetic neutral atoms. SAC B, a 181 kg. spacecraft, will be launched into orbit by a Pegasus XL rocket.

And you can see, using the old gamma technology, that it just looked like noise.

So let's look at this in the context of the entire electromagnetic spectrum, where we have gamma rays.

Analytical work has been carried out in order to calculate the detection probabilities of various gamma and neutron sensors and to learn how to combine them into distributed networks.

Turkey is also participating in the X ray astronomy satellite experiment, known as Spectrum X Gamma, under the coordination and leadership of the Russian Federation s Space Research Institute.
