But don’t you agree that up there in vacuum space and exposed to the radiation of the Sun, any human will be tanned, roasted, vaporized and killed immediately? No atmosphere or clouds or sun shades to shield you.
No, not that severe.
The actual intensity outside the atmosphere is about 1366 W/m2 and is about 1000W/m2 on earth when the sun is directly overhead.
Of course, outside the atmosphere there is much more damaging UV and shorter wavelength radiation, but nobody is ever going to be exposed directly to that.
Anyone "in space" will be in a spacecraft or in a protective suit. Radiation is still a serious hazard though, especially from solar flares.
Don’t you know that radiation inside a spacecraft orbiting Earth originates from:
1. Galactic Cosmic Rays (GCR) – charged particles from the Universe
2. Earth’s Radiation Belts (ERBs) – energetic electrons and protons
3. Solar Particle Events (SPE) – intense solar flare particles
Of course I know that!
Such GCR, ERBs and SPE radiations kill any asstronut exposed to it after 1 second.
Total idiotic garbage!
Luckily all US manned space trips 1962-2018 took place at Hollywood, CA, so nobody got hurt.
There is no business like space radiation business I know ...
Oh, aren't you just the smartest!
And when were you last in space to measure all this radiation - too recently it appears,
as you clearly haven't recovered yet.
- Galactic Cosmic Rays (GCR) – charged particles from the Universe:
Estimates are that humans unshielded in interplanetary space would receive annually roughly 400 to 900 mSv (compared to 2.4 mSv on Earth) and that a Mars mission (12 months in flight and 18 months on Mars) might expose shielded astronauts to roughly 500 to 1000 mSv.[27] These doses approach the 1 to 4 Sv career limits advised by the National Council on Radiation Protection and Measurements (NCRP) for low Earth orbit activities in 1989, and the more recent NCRP recommendations of 0.5 to 2 Sv in 2000 based on updated information on dose to risk conversion factors. Dose limits depend on age at exposure and sex due to difference in suspetability with age, the added risks of breast and ovarian cancers to women, and the variability of cancer risks such as lung cancer between men and women.
The extra dosage from GCR during the short lunar missions is not significant, but does become of great concern in longer mission such as to Mars (if it ever happens).
So Anders Björkman, you claim to know more than the National Council on Radiation Protection and Measurements - balderdash!
- Earth’s Radiation Belts (ERBs) – energetic electrons and protons:
You might read: Flat Earth Debate / Re: VERY SIMPLE QUESTION for HC believers!!! « Message by rabinoz on February 27, 2018, 06:56:18 AM » which contains a statement by James Van Allen who knows a lot more about the Earth’s Radiation Belts (ERBs) that a twerp called Anders Björkman!
And you might read Re: MOON Craters aint adding up!? « Reply #19 on: February 19, 2017, 03:09:20 PM » which list actual measured doses.
Again Anders Björkman you are totally hopeless and simply try to prop up your silly website that is of interest mainly to totally deluded conspiritards!
- Solar Particle Events (SPE) – intense solar flare particles
Solar particles are the main cause of the Van Allen Belt radiation, but only become an extreme hazard during Intense Solar Flare Events, which are comparatively rare and there is significant warning of these events.- May 1921 geomagnetic storm
- 25–26 January 1938 geomagnetic storm ("Fátima storm")
- 17–19 September 1941 solar storm
- 23 February 1956
- Late May 1967 solar storms
- March 1989 geomagnetic storm
- August 1989
- 6 April 2000
- Bastille Day event of July 14, 2000
- 11 April 2001
- Halloween solar storms, 2003
- 20 January 2005
Intense Solar Particle Events are comparatively rare and posed only a slight statistical risk to lunar missions. The plan was to "high-tail it" home if an event was expected.
Longer human space missions outside the VA belts are however at risk and adequate shielding will be essential if missions like this go ahead.
So obviously, when you claim, "There is no business like space radiation business I know ...",
maybe you do know more about "space radiation" than anything else, but that means nothing -
you seem totally ignorant about everything. At least you are consistent!
Mr Anders Björkman, the world might be a better place if you sat in your bathtub sinking all your toy boats that disseminating ignorant garbage like you do!
