Ionising radiation the big danger to astronauts
NASA says that not only does space radiation potentially put astronauts at greater risk of radiation sickness, but an “increased lifetime risk for cancer, central nervous system effects, and degenerative diseases.”
Astronauts in space are exposed to the radiation equivalent of 150 to 6,000 chest x-rays https://www.revelstokereview.com/news/morning-start-astronauts-in-space-are-exposed-to-the-radiation-equivalent-of-150-to-6000-chest-x-rays/ May 28, 2021
As noted by NASA, radiation is a type of energy that is emitted in the form of rays, electromagnetic waves and/or particles. Radiation can be seen as visible light or felt as infrared radiation. However, some forms of radiation, like x-rays and gamma rays, are not visible.
Space radiation differs from the type of radiation experienced on Earth because intergalactic radiation “is comprised of atoms in which electrons have been stripped away as the atom accelerated in interstellar space to speeds approaching the speed of light – eventually, only the nucleus of the atom remains.”
So how much space radiation are astronauts exposed to? They’re exposed to “ionizing radiation with effective doses in the range from 50 to 2,000 mSv. 1 mSv of ionizing radiation is equivalent to about three chest x-rays. So that’s like if you were to have 150 to 6,000 chest x-rays.”
With that being said, NASA says that not only does space radiation potentially put astronauts at greater risk of radiation sickness, but an “increased lifetime risk for cancer, central nervous system effects, and degenerative diseases.”

So far, the nuclear lobby has bought the hearts and minds of governments, but has not won the hearts and minds of the people. In a propaganda war, as in all wars, truth is the first victim. But there are many journalists and others out there who will counter the lies of the nuclear industry.
Today, across the world, the nuclear industry is unpopular. It is particularly unpopular with women, and with indigenous peoples. It’s unpopular with those who have suffered from it, such as the veterans who attended nuclear bomb tests, and the ‘downwinders’ who suffered from those same tests. It’s unpopular with families afflicted with cancer from uranium mining. It’s unpopular with Ukrainians and Japanese whose lives have been disrupted by nuclear disasters.
he nuclear industry is also unpopular higher up in the social food chain. Many academics, economists, scientists, and doctors are concerned about the dangers of all kinds that are intrinsic to the nuclear industry.
So who does like the nuclear industry? – careerists in the nuclear industry, careerists in politics, academia, careerists in the Murdoch media, highly paid uranium workers, communities that exist only because of mining, – (the latter can’t really afford not to support it).
The nuclear industry, following in the footsteps of the tobacco and asbestos industries will now blanket its servant mass media, and any other possible avenues – such as education, and politics, – with propaganda.
The main focus of the nuclear lobby’s propaganda? This will now be CLIMATE ACTION .
They’re spending an awful lot of money on this. Despite this huge investment in deception, the nuclear lobby is not winning.
