On the moon ”normal” humans (i.e males) will get 200 Times the Radiation Experienced on Earth, (what about females?)

Christina Macpherson’s websites & blogs

 

It is amazing that in all this propaganda for putting a woman on the moon, – no mention is ever made, of the fact that women are much more susceptible to the effects of ionising radiation, meaning that their risk of developing cancer and other illnesses is greater than it is for men. Apparently the space enthusiasts are still buying into that traditional view that the ”normal” human being is male.

Moonwalking Humans Get Blasted With 200 Times the Radiation Experienced on Earth, Smithsonian Magazine ,

The new findings will inform how much shielding future astronauts will need to safely explore the moon,  The 12 human beings who have walked on the moon were all bombarded by radiation roughly 200 times what we experience here on Earth, reports Adam Mann for Science. That’s two to three times what astronauts experience aboard the International Space Station, explains Marcia Dunn for the Associated Press (AP), suggesting that any long term human presence on the moon will require shelters with thick walls capable of blocking the radiation.

Despite the fact that the measurements, which come courtesy of China’s Chang’e-4 lunar lander, are quite high compared to what we experience on Earth, the data is quite useful for protecting future moonwalkers. According to Science, the levels of radiation at the lunar surface wouldn’t be expected to increase the risk of NASA astronauts developing cancer by more than 3 percent—a risk threshold the agency is legally required to keep its astronauts’ activities safely below.

Some forms of radiation, which is electromagnetic energy emitted in forms like heat, visible light, X-rays and radio waves, can mess with the cells inside the human body by breaking up the atoms and molecules they’re made of. On Earth, most people are familiar with ultraviolet radiation’s harmful effects on our skin, but in space, astronauts are also subjected to galactic cosmic rays, accelerated solar particles, neutrons and gamma rays, according to the research published this week in the journal Science Advances. This material can damage our DNA and lead to increased incidences of cancer or contribute to other health problems such as cataracts and degenerative diseases of the central nervous system or other organ systems.

Humanity measured the radiation astronauts on the Apollo missions experienced on their journeys to the moon, but those measurements were cumulative for each astronaut’s entire journey, per Science. To figure out the daily dose of radiation exclusively on the surface of the moon, the robotic Chang’e-4 lander used a stack of ten silicon solid-state detectors.

The renewed interest in collecting such measurements is partly because NASA has plans to send more people to the moon. The Artemis moon mission, scheduled for 2024, will feature the first woman ever to walk on the moon as well as a week-long expedition to the lunar surface and a minimum of two moonwalks, reports Katie Hunt for CNN.

Berger tells the AP that these new findings suggest the shelters needed to protect Artemis’ astronauts during such a long stay on the moon should have walls made of moon dirt that are some two and a half feet thick. Science notes that the shelter would also need an even more heavily shielded inner sanctum to protect astronauts in the event of a solar storm. Adequate shielding for this inner chamber would be roughly 30 feet of water, and would also need to be reachable within 30 minutes—the current limit of satellites’ abilities to provide astronauts with advanced warning of such hazards.

The findings aren’t exactly suprising: they are in line with calculations made using existing measurements. But they’re a crucial step towards putting people on the surface of the moon for extended periods of time. According to Science, the results confirm that with proper shielding astronauts could spend as long as six months on the moon.  https://www.smithsonianmag.com/smart-news/moonwalking-humans-get-blasted-200-times-radiation-experienced-earth-180975926/

Call to British govt to not allow restart of Hinkley Point B nuclear reactors, with cracks in their cores

Stop Hinkley 29th Sept 2020, EDF Energy has just announced that it intends to submit new safety cases to the Office for Nuclear Regulation (ONR) to re-open Reactors 3 and 4 at Hinkley Point B. It currently expects reactor 4 to return to service on 26 February 2021 and reactor 3 on 12 March 2021.

The Stop Hinkley Campaign is calling for both reactors to remain closed. Stop Hinkley spokesperson Roy Pumfrey said: “Nuclear engineer, the late John Large said more than a decade ago that it was gambling with public safety to allow reactors with cracks in their core to keep operating. (3) Every minute these reactors operate that gamble become riskier.

We call upon the UK Government to intervene and request the ONR to re-consider their unwise decisions at Hunterston B and to refuse to accept EDF’s safety cases for Hinkley Point B. It is EDF in Paris, France which will benefit from the restart of these reactors, but it is those of us who live in Somerset and middle England who are being exposed to these involuntary risks”

UK govt to give EDF a blank cheque for building Sizewell C nuclear power plant.

Dave Toke’s Blog 29th Sept 2020, It is looking increasingly likely that the British Government is about to cave-in to EDF’s demand that the British energy consumers should pay what could be massive cost overruns for building Sizewell C nuclear power plant.
But what has not been discussed so much is how the contract the Government is likely to offer EDF will reduce deployment of renewable energy schemes.
A report in The Times signals that EDF chiefs is meeting the Chancellor to complete the details for how to dress up what is in effect a blank cheque for Sizewell C. It reported that the withdrawal of Hitachi from the Wylfa site was a ‘shock’. Hitachi’s move which has been expected for a year, is not a shock to people in the energy industry. It became apparent (to me at least!) long ago that new nuclear plant can only be built if they are given an effective blank cheque (that is the promise of an unlimited supply of cash) from some state-backed energy monopoly.
EDF will be expecting the same sort of contract as given to them for Hinkley C which allows nuclear electricity generation to crowd out production from future renewable energy plant. EDF will be given so-called ‘baseload’ contracts that mean that when electricity wholesale prices are low or even negative they will still get paid the same level of high premium prices. Meanwhile future wind and solar pv projects will be effectively forced offline by the nuclear power plant because they will not receive premium prices.

Lunar base woud have to be underground, due to the danger of high radiation on the moon

After measuring radiation on the moon for the first time, scientists say a lunar base should be built underground to protect astronauts, Business Insider, AYLIN WOODWARD, SEP 30, 2020, 

  • NASA recently unveiled the plan for its Artemis program, a series of missions that would return astronauts to the moon.
  • A new study found how much radiation astronauts are exposed to on the lunar surface: a daily dose about 200 times as great as on Earth.
  • NASA wants to build a base on the moon, but the new data suggests it’d be safest to bury such a base under 2.5 feet of moon dirt to protect astronauts from radiation.
NASA wants to build a permanent base on the moon by the 2030s — a place astronauts could stay for extended visits at the lunar south pole.

But a new study found that any astronauts who go there would face levels of radiation nearly three times as high as what the astronauts on the space station deal with. Long-term exposure to enough of this cosmic radiation poses significant health risks, including cataracts, cancer, and diseases of the central nervous system.

The new research, published last week in the journal Science, calculated for the first time what a moonwalker’s daily dose of radiation would be.

“If you think about people staying on the moon for extended periods of time — say, on a scientific research station for a year or two — then these levels start getting problematic,” Robert Wimmer-Schweingruber, an author of the new study, told Business Insider.

The solution, he said, would be to build any lunar base beneath the moon’s surface.

“Covering your habitat with sufficient amounts of lunar dirt should do the trick,” Wimmer-Schweingruber said.

The first study to calculate radiation on the moon

Apollo astronauts carried radiation-measuring instruments on their missions in the 1960s and ’70s, but those dosimeters could tell scientists only the total amount of radiation the astronauts were exposed to throughout their time in space, from blasting off to landing, not just on the moon.

Wimmer-Schweingruber’s team was able to document daily radiation levels on the moon’s surface by analysing data collected by China’s Chang’e 4 spacecraft, which landed in January 2019………

Astronauts on the moon, meanwhile, face a daily radiation level five to 10 times as high as transatlantic fliers, since the moon doesn’t have the shield that Earth does.

So an astronaut on the lunar surface would be exposed to 1,369 microsieverts of radiation per day, about 200 times the daily level on Earth. ……….. https://www.businessinsider.com.au/radiation-on-the-moon-lunar-base-should-be-buried-2020-9?r=US&IR=T

One more Utah city withdraws from NuScam small nuclear reactor project

Kaysville withdraws from nuclear power project. Post Register, By NATHAN BROWN nbrown@postregister.com

    Sep 28, 2020   One more Utah city has withdrawn from a project to build 12 small nuclear reactors west of Idaho Falls.

The Kaysville City Council voted unanimously a week-and-a-half ago to withdraw from the Carbon Free Power Project, although the resolution left the door open for the city to hold a special meeting to rejoin the project if anything changes……….

Lehi and Logan have also withdrawn from the Carbon Free Power Project over the past month-and-a-half, citing potential risks to local taxpayers if costs go up. There are still more than 30 cities and power systems, including Idaho Falls, that are part of it, and the members have until Oct. 31 to recommit to the project’s next phase by approving the new budget. Utah Associated Municipal Power Systems is waiting for the U.S. Department of Energy to give final approval to a promised $1.4 billion to support the project.  ……. https://www.postregister.com/news/government/kaysville-withdraws-from-nuclear-power-project/article_fbb6f15e-e8c6-5207-b6e9-bbf632538c85.html

Offshore wind energy to replace more than half of the nation’s generation capacity by 2050

Japan’s offshore wind backers see clean heir to coal and nuclear,   Japan Times, BY AYA TAKADA, BLOOMBERG, Sep 30, 2020

Offshore wind power in Japan will be able to replace more than half of the nation’s generation capacity forecast to retire by midcentury, according to an industry group promoting its developments.

The capacity of Japan’s offshore wind farms could total 90 gigawatts by 2050, equivalent to 60 percent of the fossil fuel and nuclear facilities expected to be closed by that time according to Shigehito Nakamura, a managing director of the Japan Wind Power Association.

Japan is seeking cleaner ways to feed its energy-hungry but resource-scarce economy, the world’s biggest after the U.S. and China. It’s reliance on fossil fuels faces resistance over climate change concerns, while its massive nuclear fleet is at risk of being abandoned due to widespread opposition to the technology following the 2011 Fukushima disaster.

The 90 gigawatts target for offshore wind is ambitious. The association expects that wind power, including onshore facilities, could account for one-third of the nation’s total power generation in 2050. Capacity in the U.K., the world’s top operator of the technology, is currently about 10.4 gigawatts.

Offshore wind, which the government is seeking to deploy in greater numbers in the coming years, could help replace facilities built during Japan’s economic boom from the 1960s to the 1980s. Those are now due for retirement at an average pace of 5 gigawatts a year over the next few decades, the association estimates.

Kimio Yamaka, a director at the Energy Strategy Institute in Tokyo, said offshore wind is a realistic option for new capacity as the government plans to reduce the share of coal power in the country’s generation to 26 percent by 2030, from 32 percent in the year to March 2019, while replacing or expanding nuclear plants is unlikely. ….

The Economy, Trade and Industry Ministry has started reviewing this target as it prepares to revise the plan next year. METI estimates that offshore wind projects can run at 95 percent utilization, a much higher level of reliability than onshore renewables.

The government plans to hold its first auction for fixed-foundation offshore wind projects in November. Winners will be announced around summer 2021 after the feasibility and economics of the proposed projects are assessed, according to Juntaro Shimizu, the director at the renewable energy division of METI……https://www.japantimes.co.jp/news/2020/09/30/business/corporate-business/offshore-wind-coal-nuclear-energy/
