Cosmic ray spallation, also known as the x-process, is a set of naturally occurring nuclear reactions causing nucleosynthesis; it refers to the formation of ...

Cosmic-Ray Induced Nuclear Disintegrations at 11000 Meters

The equivalent absorption depth in air of the star-producing radiation is determined as 125±8 g/ c m 2 by means of the photographic emulsion technique.

Cosmic ray radiation effects caused by proton-induced fragmentation

In space, radiation effects in which a large amount of energy is transferred by a single particle are observed. These effects can be caused by either the ...

Cosmic ray-induced neutron : Research & Development - Hitachi

When high-energy particles flying in outer space (cosmic rays) impact the Earth's atmosphere, they cause nuclear reactions to produce neutrons—called cosmic ray ...

Cosmic-ray-induced fission of heavy nuclides: possible influe..|INIS

Samples having typical lunar heavy element contents can yield apparent fission track ages which are too high by a factor of up to approximately 13 due to cosmic ...

Lecture 13 Radioactivity in the Atmosphere

Cosmic ray induced mutation? Cosmic ray triggers mutation processes by affecting the molecular structure or sequence of DNA sections, causing the mutations that.

Cosmic-Ray Produced Radionuclides in the Environment

Radionuclides are continually produced by interactions of cosmic rays with the atmosphere, hydrosphere and lithosphere.

Nuclear Fusion Power

In addition, nuclear fission reactors use solid fuel which is denser than a thermonuclear plasma, so the energy released is more concentrated. Also the neutron ...

Revisiting the cosmic-ray induced Venusian ionization with the ...

Cosmic ray bombardment represents a major source of ionization in planetary atmospheres. The higher the energy of the primary cosmic ray particles, the deeper ...

Cosmic Rays | NCEI

When the secondary cosmic rays interact in the monitor, (actually in lead surrounding the counters) they cause nuclear disintegrations, or stars. These ...

Detecting special nuclear material using muon-induced neutron ...

In this report, we explore a new technique that neutrons generated via interactions with cosmic-rays to detect the presence of fissile material. It is well ...

Investigating the biological potential of galactic cosmic ray-induced ...

I hypothesize that Galactic Cosmic Ray (GCR)-induced radiation-driven chemical disequilibrium can be used for metabolic energy by extant life, and host ...

On the possibility of galactic cosmic ray-induced radiolysis-powered ...

Galactic cosmic rays (GCRs) are charged particles, mostly protons, originating beyond the Solar System [21–23]. They have relatively lower flux ...

How cosmic rays may have shaped life - Stanford Report

Cosmic rays are an abundant form of high-energy radiation that originates from various sources throughout the universe, including stars and ...

AMES COLLABORATIVE STUDY OF COSMIC RAY NEUTRONS

One significant feature of their spectrum is a peak at a few MeV, attributed by the authors to nuclear evaporation processes. Only a few measurements of neutron ...

Cosmic ray induced ionization in the atmosphere: Full modeling and ...

Energetic cosmic rays (CR) initiate a nucleonic-electromagnetic cascade in the atmosphere, affecting its physical-chemical properties, in ...

How are nuclear thermal reactors designed for cosmic rays in space?

This implies that neutrons are not a significant constituent of cosmic rays. Since fission is driven by neutron absorption, reactor control is ...

Telescope Array detects second highest-energy cosmic ray ever

On May 27, 2021, the Telescope Array experiment detected the second-highest extreme-energy cosmic ray. At 2.4 x 1020eV, the energy of this ...
