The Energetic Gamma Ray Experiment Telescope (EGRET) on the Compton Gamma Ray Observatory has detected gamma rays from the Moon as it passed through the instrument field of view several times between 1991 and 1994. The average flux, (4.7 \pm 0.7) \times 10^-7 ph(>100 MeV)/cm^2s, and the energy spectrum of the lunar gamma radiation are consistent with a model of gamma ray production by cosmic ray interactions with the lunar surface, and the flux varies as expected with the solar cycle. Although the same processes may occur on the Sun, EGRET does not detect the quiet Sun. The upper limit, 3.0 \times 10^-7 ph(>100 MeV)/cm^2s, does not contradict calculations of the expected solar gamma-ray flux. Thus, in high-energy gamma rays, the Moon is brighter than the quiet Sun.
I am insinueting that the report is a big lie YES.
I will have to get numbers YES.

Is ten million electron volts a high energy level? The reader isn't told. It sounds like a big number. Put a nine-volt battery on your tongue and you'll get an unpleasant but harmless jolt. You see sparks from a 12-volt battery when you jump-start a car. We take great pains to shield ourselves from the 110-volt current in our houses because we know it can kill us. So ten million electron volts must be an enourmous amount of unquestionably fatal energy. Right?
Well, no. The "electron volt" (eV) is not equivalent to the common "volt" that measures household electricity. Instead it's the amount of energy picked up by a single electron as it passes through an electrical potential of one volt. We realize that's not a very helpful definition to the layman, but it takes the equivalent energy of about 620,000,000,000,000 million electron volts (MeV) per second to light up a 100-watt light bulb. The figure is obviously cited because it's a big scary number, but it's like saying an automobile weighs 2.3 billion milligrams. A large number, but a small unit. The very large figure given for the light bulb is explained by knowing that each individual electron that participates in the operation of a light bulb has a fairly small energy level, but there are billions and billions of electrons involved. In radiation terms this is called a high "flux". In space the individual electrons can have very high energy levels, but there aren't as many of them. The flux is much smaller.
But solar events do in fact produce dangerous radiation. They have been known to knock out communications satellites and even disrupt terrestrial communications. But in order to correlate the conspiracists' numbers with the likely threat, we have to know what kind of particle the number refers to. A 10 MeV electron is relatively harmless, while a 10 MeV proton might be a cause for concern. But again, the energy level is only half the story. You also have to know the particle flux.
The dosage figures, which take into account both energy and flux, are likely to be fairly accurate. But the conspiracists make the fundamental error of multiplying these worst-case exposure characteristics by the 15-per-day figure, or 1,400 total figure, representing the number of merely detectable events, thereby arriving at what they believe to be the exposure level of a typical mission to the moon. If we stick with the earthquake analogy, it would be like counting the dozens of microquakes that occur on a daily basis and multiplying that number by the 7.0 or 8.0 Richter magnitudes for a single major earthquake, and then presuming that massive devastation must have taken place during those microquakes.
The shielding tenth value thickness for 1 Mev gamma of: lead is 1.5 inches, concrete is 12 inches, and water is 24 inches.
The shielding half value thickness for 6 Mev gamma of: lead is 0.7 inches, steel/iron is 1.3 inches, concrete is 8 inches, and water is 16 inches.
The shielding tenth value thickness for 6 Mev gamma of: lead is 2 inches, steel/iron is 4 inches, concrete is 24 inches, and water is 48 inches.
For lines and equipment containing reactor water, or primary steam with hold-up times of less than five minutes, you would use 6 Mev gamma 1/10 shielding ( lead 2", water 48")
