1. Sulphur Mountain Cosmic Ray Station National Historic Site of Canada Remains of high altitude geophysical laboratory

2. In terms of stopping power per gram, the ideal material for stopping cosmic-ray protons is hydrogen.

3. 22 When a cosmic-ray encounters solid matter then in most cases it penetrates only a few millimetres and leaves a detectable track.

4. If Carbon 14 is being produced in the upper atmosphere by cosmic ray bombardment at a constant rate, then Carbon 14 must be accumulating in the world

5. In earth's atmosphere, Ar-39 is made by cosmic ray activity, primarily with Ar-40. In the subsurface environment, it is also produced through neutron-capture by K-39 or alpha emission by calcium .

6. In the extended magnetosphere of planets, antiprotons can be produced from the decay of cosmic ray Antineutrons which are generated from interactions between cosmic rays and matter located in the vicinity of the planet

7. To reach this goal, researchers will sample rocks from key sites around the world, expose elements to nuclear beams in high-energy accelerators, and count cosmic-ray impacts with detectors flown to high altitudes in aircraft.
