[Gizmodo] Thunderstorms contain ‘dark lightning,’ invisible pulses of powerful radiation - Page 3

post #21 of 34

Unknown to Franklin but now clear to a growing roster of lightning researchers and astronomers is that along with bright thunderbolts, thunderstorms unleash sprays of X-rays and even intense bursts of gamma rays, a form of radiation normally associated with such cosmic spectacles as collapsing stars.

Gamma rays? *waits for somebody to turn into the Hulk mid-flight*

gamma and xray from lightning? this just makes me think of lightning in weirder ways.

also its very scary to hear how a dark lightning strike is the equivalent to 10 doses of chest x rays. luckily you'd have to be very close to the thunderstorm to get hit by dark lightning

But according to Dwyer's calculations, they might receive in an instant the maximum safe lifetime dose of ionizing radiation - the kind that wreaks the most havoc on the human body.

Seriously - There's no such thing as a "safe" lifetime dose. Radiation damage is cumulative, and the shorter the time period of exposure, the more dangerous it is. In other words, the less exposure you receive, the more time your body has to repair the damage to your DNA.

For example, an exposure of 2000 Rad in an hour will kill you. (for reference, 1 rad = 0.01 Gy = 0.01 J/kg). 500 rad over 5 hours will likely kill you. 500 rad total exposure over the remainder of your life might very well go unnoticed.

For example:

Quote:
This criticality exposed the 37-year-old Peabody to a fatal radiation dose of 10,000 rad (100 Gy). He died 49 hours after the incident.

Ninety minutes later a second excursion happened when a plant manager returned to the building and turned off the agitator, exposing himself and another administrator to doses of up to 100 rad (1 Gy) without apparent ill effect.

wow really cool find, thanks. I love this stuff. I work in the Pilbara, up north of western Australia and after 3 years of sucking dust, dirt and working my arse off, it all pays off when we get one of our awesome summer thunderstorms. the electric show is amazing, lightning is one of most favourite things to experience, can watch it for hours.

if I had a superpower, I would be able to shoot lightning. nuff said

That really is quite amazing/interesting/scary, the fact that you could be in an airplane and potentially be exposed to a lifetime worth of radiation is bonkers.

This is pretty incredible. Definitely going to read more into it.
