Observations from high-flying aircraft revealed that thunderclouds act as natural particle accelerators, emitting energetic ...

Gamma rays are used for sterilising food and medical instruments, and in the treatment and detection of cancer. Ultraviolet waves can cause damage to skin cells and eyes, and increase the risk of ...

shortest of all known rays, the gamma rays given off by radium. On the infra or long wave side of visible light come infrared, then longer heat waves (16 mil-lionths to 12 thousandths of an inch ...

Like ultraviolet radiation and X-rays, gamma rays can kill microorganisms and are used to sterilize food and other objects, such as medical instruments and equipment. Gamma radiation is also a ...

Light, heat, radio transmissions, and medical X-rays may not seem ... ultraviolet radiation, and X-rays. The tour ends with gamma rays, the potentially deadly radiation discussed in the program ...

Gamma-ray bursts (GRBs) are the most energetic events ever observed in the universe. These powerful outbursts can shine a ...

Gamma rays are also used to produce medical images and to sterilise medical instruments, in a similar way to X-rays. They are also used to sterilise food, killing bacteria in fresh fruit and ...

Neutron-capture prompt-gamma activation analysis (PGAA) is particularly valuable as a non-destructive nuclear method in the measurement of elements that do not form neutron capture products with ...

we will establish an imaging method to visualize line X-ray gamma-rays from activated materials in general. We will expand this method to the fields of space, medicine, and pharmacology, and establish ...
