What is the gamma ray spectrometer on Mars?

The gamma-ray spectrometer on NASA's Mars Odyssey Orbiter detects and maps these signatures , such as this map (below) showing hydrogen concentrations of Martian surface soils.

Can gamma rays be reflected?

Unlike optical light and x-rays, gamma rays cannot be captured and reflected by mirrors. Gamma-ray wavelengths are so short that they can pass through the space within the atoms of a detector. Gamma-ray detectors typically contain densely packed crystal blocks. As gamma rays pass through, they collide with electrons in the crystal.

How do gamma rays kill cancer cells?

In a procedure called gamma knife surgery, several concentrated gamma rays are directed at the growth to kill cancer cells. The beams are directed from different angles to concentrate radiation on the growth while minimizing damage to the surrounding tissue.

What is gamma radiation?

Gamma radiation is a highly penetrating electromagnetic radiation, which arises from the spontaneous transformation (“decay”) of the atomic nuclei of many naturally occurring or artificially occurring radioactive nuclides.

What are the rays that are emitted by radioactive elements?

The rays emitted by radioactive elements are named according to their power to penetrate various materials, using the first three letters of the Greek alphabet: alpha rays , which penetrate the least, followed by beta rays and gamma rays, which are the most penetrating. Rutherford also realized that gamma rays were not deflected (or at least not easily deflected) by magnetic fields, another property that distinguished them from alpha and beta rays.

Why do gamma rays sound foreign?

Gamma rays may sound foreign to us because of their form in the form of rays (radiation) and also because gamma rays can only be found in nuclear processes. Maybe what we often hear is gamma rays for the treatment of cancer, tumors and other diseases.

What is the Greek word for gamma rays?

Often denoted by the Greek letter gamma, ). Gamma rays are an energized form of electromagnetic radiation produced by radioactivity/other nuclear/subatomic processes such as electron-positron annihilation.

Which type of electromagnetic wave has the strongest penetrating power?

The properties possessed by gamma rays are high energy so that their penetrating power is very strong. Gamma rays have the strongest penetrating power compared to the waves that fall into the electromagnetic wave group. Gamma rays can penetrate iron plates up to several centimeters thick.

When were gamma rays observed?

In 1914, gamma rays were observed bouncing off the glass surface, proving that it was electromagnetic radiation.

What are the benefits of gamma brain waves?

Gamma brain wave benefits are many. They open up a whole new state of awareness and consciousness within our minds. We see, hear, touch, and think better with increased gamma brain wave activity. We’re more focused, but not on a single thing — on everything, on all of our experiences within a given moment.

What is the effect of gamma brain wave activity?

People who display high gamma brain wave activity are generally happier and calmer than those with reduced gamma brain wave activity. Increased gamma brain wave activity functions as an antidepressant; people suffering depression typically have lower gamma activity.

What is gamma brain wave?

Gamma brain waves are produced when multiple parts of the brain are active and communicating. High gamma brain wave activity heightens the senses — better taste, sight, hearing, even smell. You perceive reality sharper and clearer than ever before when your brain is alive with gamma wave activity.

What is the highest frequency brain wave?

Gamma brain waves are the highest-frequency brain waves known — for now. While brain waves were first detected and studied in the early 20th century, it wasn’t until the late 1980s that gamma brain waves were discovered. High-frequency brain waves like beta waves are typically associated with highly alert states.

Which brain waves are most active during meditation?

Alpha brain waves are particularly active during meditation. Delta brain waves, the lowest frequency, can be achieved through particularly deep meditative states. But gamma brain waves, with their incredibly high frequencies, can also be stimulated by meditation.

Do gamma waves have amplitude?

Surprisingly, no. In fact, gamma brain waves are associated with creativity and complex communication between various parts of the brain. The frequency of the waves are high, but their amplitude is low, like an excited whisper. Here’s how Gamma Waves sound:

Does high frequency brain wave cause anxiety?

High-frequency brain waves like beta waves are typically associated with highly alert states. Too much beta wave activity is associated with feelings of stress and anxiety. So it would stand to reason that even higher frequency brain waves — between 25-100hz — would produce more anxiety, surely? Surprisingly, no.
