For over a decade, a star system on the verge of unleashing a deadly gamma ray burst appeared to have its guns trained on ...

Previous research also indicated that Earth looks down the axis of this system, known as Wolf-Rayet 104, raising concerns ...

The discovery, and the newly identified position of the binary companion, mean we no longer have to fret about the Pinwheel ...

This site presents the energy and photon intensity of gamma rays as seen in thermal-neutron capture in two tables, one in ascending order of gamma energy and a second organized by Z, A of the target.

SPACE is a deadly place – and we're all living at its mercy on a little blue rock. Thankfully we know that asteroid 2024 YR4 won't be crashing into us after all, but that's not the only space ...

Using 16 years of data from NASA's gamma-ray detecting Fermi spacecraft, astronomers have discovered that "microquasars," systems in which a black hole is slowly devouring a star, may be small ...

Broser and Kallmann 1 have shown that mono-energetic alpha-particles give pulses of the same height in a scintillation counter, and that the pulse-height is proportional to the energy of the alpha ...

An isotope emits gamma rays that easily pass through the body to a detector outside the body, for example a ‘gamma camera’. In this way, the radioactive isotope can be followed as it flows ...

All types of radiation become less intense as they travel further away from the radioactive material. This is because the particles or rays become more spread out. The thicker the substance, the ...
