Radioactivity of the Lunar Surface
Science, 1966Diffusion of radon and thoron from the lunar surface provides a mechanism for production of a radioactive surface layer on the moon. If the radon and thoron flux from the lunar surface is equal to that measured at the earth's surface, the equilibrium activity of this surface layer is estimated as approximately 1 microcurie per square meter, due to ...

Seismic refraction data obtained at the Apollo 14, 16, and 17 landing sites permit a compressional wave velocity profile of the lunar near surface to be derived. Although the regolith is locally variable in thickness, it possesses surprisingly similar seismic characteristics.

The adverse environment of the lunar surface requires the implementation of unique land vehicle navigation techniques, concepts, and components to perform postulated future lunar surface navigation functions. Subject to the lunar environmental constraints, three generalized lunar surface navigation concepts are modeled and analyzed.

Magnetometers have been placed on the moon by astronauts of the Apollo 12, 14, 15, and 16 missions. These instruments have measured permanent fields due to fossil magnetic material in the lunar crust and transient fields due to electrical eddy currents generated in the lunar interior.

The lunar surface magnetometer is one of five instruments in the Apollo lunar surface experiments package (ALSEP). It measures three components of the vector magnetic field in the range 0 to 400? with a resolution of 0.2? and a frequency response from dc to 3 Hz.
