The gamma-ray spectrometer was designed to detect these types of rocks.

Jeff's church group has invested in six gamma-ray spectrometers to measure radiation absorbed into food.

The gamma-ray spectrometer operated until 1 June 1980, when its cryogen was exhausted.

The gamma-ray spectrometer boom was stowed and all the equipment was made safe.

At Rocky Flats, the residue samples were loaded into a gamma-ray spectrometer.

Four hours later, they were in Dimona, the Israeli nuclear 'research' facility, where there was another gamma-ray spectrometer.

All of the stratigraphic details, natural radiation measurements taken with a gamma-ray spectrometer and chemical analyses available appear for each section.

A lithium-drifted germanium gamma-ray spectrometer was used to resolve the activities of the irradiated samples.

The Determination zone was discovered during follow-up of radiometric anomalies located by an airborne magnetic–electromagnetic– gamma-ray spectrometer survey.

To do so, the probe carries a camera, a gamma-ray spectrometer, a near-infrared spectrograph, a magnetometer and a laser range finder, among other instruments.

Fortunately, the spacecraft's solar panels were bathed in sunlight and able to power NEAR's gamma-ray spectrometer.

Messenger's studies of Mercury's past involved using the ship's gamma-ray spectrometer and X-ray-emissions detector to analyze the composition of the planet's surface.

Airborne sensitivities are determined from flights at different altitude over a calibration range whose ground concentrations are measured with a calibrated portable gamma-ray spectrometer.

Development of techniques The project to demonstrate and evaluate the use of a towed seabed gamma-ray spectrometer in Far Eastern waters continues.

The Geological Survey of Canada has been mapping natural and anthropogenic radioactivity, using aerial and field-portable gamma-ray spectrometers.

In the last 5 years alone, Fugro Airborne Surveys has flown over 1 million line kilometres of airborne gamma-ray spectrometer surveys.

However, global-scale surface composition can be inferred from the Mars Odyssey gamma-ray spectrometer (GRS).

The first was a cryogenically cooled germanium (Ge) high-resolution gamma-ray spectrometer, while the C2 and C3 experiments were large cosmic-ray instruments.

One instrument containing a gamma-ray spectrometer automatically analyzes faint radiation that a container might emit during a theft and quickly determines whether nuclear fuel is concealed inside.

The Psyche spacecraft would use solar electric propulsion, and the notional payload would be an imager, a magnetometer, and a gamma-ray spectrometer.

Gamma-ray spectrometers have been widely used for the elemental and isotopic analysis of airless bodies in the Solar System, especially the Moon and Mars.

HEAO 3 included three scientific instruments: the first a cryogenic high-resolution germanium gamma-ray spectrometer, and two devoted to cosmic-ray observations.

"This hypothesis is not likely to be true," the University of Arizona's William Boynton, principal investigator for Mars Odyssey's gamma-ray spectrometer, wrote in an email.

Some radionuclides produce discrete γ-rays that produce energy between a few KeV to 10 MeV which can be measured with a gamma-ray spectrometer.

Most recently, the composition of this basin has been further constrained by the analysis of data obtained from a gamma-ray spectrometer that was on board the Lunar Prospector mission.
