Ionizing and radiation

Ionizing ( or ionising ) radiation is radiation composed of particles that individually carry enough energy to liberate an electron from an atom or molecule without raising the bulk material to ionization temperature.
Ionizing radiation is generated through nuclear reactions, either artificial or natural, by very high temperature ( e. g. the corona of the Sun ), or via production of high energy particles in particle accelerators, or due to acceleration of charged particles by the electromagnetic fields produced by natural processes, from lightning to supernova explosions.
Ionizing radiation includes cosmic rays, alpha, beta and gamma rays, X-rays, and in general any charged particle moving at relativistic speeds.
Ionizing radiation includes some portion of the ultraviolet spectrum, depending on context.
Ionizing radiation is ubiquitous in the environment, and comes from naturally occurring radioactive materials and cosmic rays.
Ionizing radiation is invisible and not directly detectable by human senses, so instruments such as Geiger counters are usually required to detect its presence.

The lack of scientific unanimity on the effects of radiation is due in part to insufficient data covering large population groups, from which agreed-on generalizations could be drawn.

This result suggests a very high temperature at the solid surface of the planet, although there is the possibility that the observed radiation may be a combination of both thermal and non-thermal components and that the observed spectrum is that of a black body merely by coincidence.
For the case of Jupiter, the radio emission spectrum is definitely not like the spectrum of a black-body radiator, and it seems very likely that the radiation reaching the earth is a combination of thermal radiation from the atmosphere and non-thermal components.
Mars has been observed twice at about 3-cm wave length, and the intensity of the observed radiation is in reasonable agreement with the thermal radiation which might be predicted on the basis of the known temperature of Mars.
