Consequently, in living tissue, neutrons have a relatively high relative biological effectiveness, and are roughly ten times more effective at causing biological damage compared to gamma or beta radiation of equivalent energy exposure.

The very lowest energy range of UV between 315 nm and visible light ( called UV-A ) is not blocked well by the atmosphere, but does not cause sunburn and does less biological damage.

When alpha particles emitting isotopes are ingested, they are far more dangerous than their half-life or decay rate would suggest, due to the high relative biological effectiveness of alpha radiation to cause biological damage.

Part of the neutrino flow reaching the Earth comes from the thermonuclear reactions that fuel the Sun, but there are too few solar neutrinos with high enough energy to cause appreciable biological damage, Collar said.
15.
Experiments in 2007 at Brookhaven National Laboratory's NASA Space Radiation Laboratory ( NSRL ) suggest that biological damage due to a given exposure is actually about half what was previously estimated : specifically, it turns out that low energy protons cause more damage than high energy ones.

Beginning in 1980, the British-born scientist was in charge of the global effort to assess the " eating away " by manmade chlorofluorocarbons _ CFCs _ of atmospheric ozone, which helps protect life on Earth from harmful ultraviolet rays that can cause skin cancer and other biological damage.

Lucid may have lost as much as 25 to 30 percent of the mass in such extensor muscles as the calves and thighs, says physiologist Kenneth Baldwin of the University of California, Irvine, who chairs a NASA panel looking for ways to minimize the biological damage from spaceflight.

As a result, most historic glazing that has been left in situ is subjected to a constant onslaught of harmful conditions including ( but not limited to ) : UV light from sunlight, extreme weather conditions, indoor and outdoor man-made pollution, and biological damage caused by pests such as pigeons, bats, and various micro-organisms ( Rauch 2004, 3 ).

"You don't have to have biological damage to create disorientation or incapacitation, " said Capt . Bill Connor, a retired Delta Air Lines pilot and chairman of the private industry group studying the effects of laser light use on aircraft . " We don't want to shut the laser industry down, but all it takes is one accident, then everybody loses ."
