While there's no imminent danger from cosmic radiation, according to the International Commission on Radiological Protection (ICRP), Mertens says: "Each exposure incrementally increases your probability of developing fatal cancer.
The relationship between solar activity, cosmic radiation, and cloud cover is well attested.
1: The observed spectrum of cosmic radiation in the energy range [10.sup.8] - [10.sup.20] eV.
reinhardtii, often studied as a model for photosynthesis, spent 15 days in orbit getting doses of cosmic radiation while under light and temperature conditions that would ensure growth on earth.
Having been a exposed to cosmic radiation in space, a group of astronauts (Ioan Gruffudd, Michael Chiklis, Jessica Alba and Chris Pine) receive odd superpowers.
That's assuming they even get that far and that the astronauts on board haven't gone out of their minds asking "Are we there yet" on the two year, 35 million mile journey, been fried to death by galactic cosmic radiation, or asphyxiated by the toxic fumes from their own poo.

Nine presentations from the July 2011 school introduce the role of neutrinos in understanding cosmology and stars, the origin and nature of cosmic radiation, the design of low-energy neutrino detectors, and the physics and operation of neutrino telescopes.
Natural sources of radiation on the ground include terrestrial sources such as radon in the air, cosmic radiation from space, and even the decay of potassium in the human body.
Fantastic Four Sky Movies Action/Thriller, today, 6.10pm A scientist and four members of his crew develop superhuman powers after exposure to cosmic radiation on a mission to study an energy storm in space.
"This changes every now and then and this time it has affected cosmic radiation and contributed to more cloud cover, leading to somewhat milder temperatures," he said.
The former includes cosmic radiation (high-energy particles originating outside Earth's solar system) and radon in rocks; the latter includes medical X-rays, CT scans, and even travel in airplanes at high altitudes, where the thinner atmosphere offers less protection against incoming cosmic radiation.
The research suggests the dormant bugs could easily have survived the long journey through space, despite high levels of cosmic radiation.
The amount of exposure from a single scan is less than the normal exposure every person receives each hour from natural everyday sources, such as the naturally occurring isotopes in all materials or from cosmic radiation. In the United States, the annual average radiation exposure from natural sources is 2.95 mSv--25,000 times the amount received from a single backscatter scan.
The original [D.sub.A] in the sample is obtained from the negative intercept of the regression line with the dose axis; is estimated as being the total radiation provided by all radioactive elements present in a sample and soil and also cosmic radiation (Ikeya 1993; Jonas 1997; Walker 2005; Grun 1989).
