Radiation in General Radiation in general can be defined as energy in transit in the form of high-speed particles and electromagnetic waves. Radiation can be divided into the following categories in terms of its effect on the matter: Ionizing (UV, X and γ-rays, protons, neutrons and heavier highly energetic particles.) Non ionizing (microwaves, radio waves, and visible light.)

What on earth is space radiation? Space Radiation Cosmic Rays Mainly protons Energies up to eV Solar Radiation Electromagnetic Radio to X-rays Particulate Low energy Mainly protons & e - Energy: Mev-GeV High Energy Protons & a’s Energy: MeV-TeV Trapped particle Radiation protons & e- Energy: Mev-GeV

Cosmic Rays Discovered in 1912 by the Austrian Victor Francis Hess but their origin remains an unsolved mystery until now!

Trapped Radiation

Solar Radiation Solar particle events are injections of energetic electrons, protons, alpha particles, and heavier particles into interplanetary space. The solar wind contains ions from almost every element in the periodic table; however, it consists primarily of protons and electrons.

Why is space radiation harmful?

Type of DamageProspects for DNA Repair Single strand break in the DNA Can usually be repaired and normal cell function restored Breaks in both DNA strands Usually damage is to severe for repair. The cell dies. Chemical change or mutation Cannot be repaired. Cancer may result or a mutated offspring if this occurs in a sperm or egg cell

In Conclusion Space Radiation Cosmic Rays Mainly protons Energies up to eV Solar Radiation Electromagnetic Radio to X-rays Particulate Low energy Mainly protons & e - Energy: Mev-GeV High Energy Protons & a’s Energy: MeV-TeV Trapped particle Radiation protons & e- Energy: Mev-GeV
