Human Health concerns

[sergiof]

Dear fellows,

The negative impacts from Xray, UV radiations and particle radiations on human being are well known nowadays. However, I guess wether there is a scientific study on:

1) health injuries on people on the streets from solar radiations during solar storms?

2) clouds and rain impacts on the reduction of the radiation that reaches us at the sea level?

3) wether people in the South America Anomaly area would be more affected than people elsewhere?

After so many workshops promoted by NOAA, NASA, and the Dept of Commerce on a probable solar crisis in 2012, I consider healthy to gather as much information as possible... beforehand!

Regards,

Sergio

Sergio,
Don't worry about this. The Earth's atmosphere is virtually opaque to electromagnetic radiation, with notable exceptions for "transparent" bands like visible light and radio wave spectrums. X-ray and gamma radiation, for example, is quickly absorbed within a few hundred meters of the source.

Lucky for us, else life could not have evolved with all that high energy junk radiated by the Sun and Cosmos.

However, there is one hazard that does expose a few humans on Earth to some risk: terrestrial gamma ray flashes (en.wikipedia.org/wiki/Terrestrial_gamma-ray_flash)

Fortunately, the risk is extremely low, unless you happen to be in an aircraft flying through a thunderstorm where these TGF's are spawned. Really nothing to worry about, even if you're a frequent air traveler, because pilots tend to avoid these places.

Sergio, study up on the controversy between the Linear, No Threshold hypothesis and the Radiation Hormesis hypothesis. The Wikipedia is a good first reference.
