Radiation at Altitude

Finally, a space weather site that provides data on Radiation at Altitude

Some of you may remember my citizen scientist efforts at Geiger data gathering at altitude on airplane flights.    What was most interesting was that by holding the Geiger against the leg, you can block half the beta and all the alpha. 

My testing showed a significant amount of Beta in the "jet stream".   Cosmic is gamma, do this beta is foreign, man made.   Search the site to find those.   Use the search box.
-----------------------------------------------------
For the testing below, this guy is in charge.    For a $500 donation, they will do a specific test for you.    I want to document his name and email, because after the holidays I want to suggest some tests that may leap frog on my own testing on the trademarked "beta blocker" leg test, or the orientation testing.

Radiation levels peak at the entrance to the stratosphere in a broad region called the "Pfotzer Maximum." This peak is named after physicist George Pfotzer who discovered it using balloons and Geiger tubes in the 1930s. Radiation levels there are more than 80x sea level.

Note that the bottom of the Pfotzer Maximim is near 55,000 ft. This means that some high-flying aircraft are not far from the zone of maximum radiation. Indeed, according to the Oct 22th measurements, a plane flying at 45,000 feet is exposed to 2.79 uSv/hr. At that rate, a passenger would absorb about one dental X-ray's worth of radiation in about 5 hours.

The radiation sensors onboard our helium balloons detect X-rays and gamma-rays in the energy range 10 keV to 20 MeV. These energies span the range of medical X-ray machines and airport security scanners.

stock here--as expected, flying at night is not protection from Cosmic, because it comes mainly from deep space, all around us.   In all directions

Space Weather is good stuff.    It explains a lot of things that happen on the Earth, especially things that lying scientists attribute to other causes.    interested?   Dive in, if I told you the truth, you wouldn't believe me.

  1. What would you think would happen to air travel if flight crews were required to openly display dosimetry?

    Its all about balancing risk and benefit.

    That increase in cancer rate since 1900? Lots of reasons.

    Check the cancer rates of flight crews vs nuclear workers.

    1. Speaking of risk versus benefit,
      what cumulative duration of flight might it take during a Solar Minimum (for instance - presuming highest Cosmic Radiation levels at altitude) for cataracts to result?

      The eyes are the most sensitive external organ to radiation, if i remember correctly. What was it ... 170mSv cumulative external exposure to potentially cause cataracts in the lens?

      Quote: "For many years radiation-induced cataracts were considered unlikely by most radiologists. Recent data suggest that the likelihood is much higher than previously thought, and the International Commission on Radiological Protection has suggested lower exposure limits." http://www.ncbi.nlm.nih.gov/pubmed/25247963

      Nobody wants pilots literally flying blind.
      Perhaps they should collect dosimetry data, for shits and giggles.

      At least that way if a massive burst hits and flight crews are alerted, they may be able to reduce altitude as needed (if necessary).


      If i am wrong in any way, constructive criticism is welcome, by the bye.

    1. Sheesh, bro, just show up and pot shot lies and the easy deceptions that we are long past biting on?

      Come on, grow up. Argue like an engineer or scientist, not just the blatant bullshit.
