Shielding Materials Daniel R McAlister PhD PG Research Foundation Inc 1955 University Lane Lisle IL 60532 USA Revision 6 1 June 18 201 8 Introduction Attenuation or s hielding of gamma r. The diffuse attenuation coefficients for downward irradiance K and the irradiance reflectances R as derived from hyperspectral downward and upward irradiance measurements exhibit v ery uncommon values that reflect the exceptional clarity of this h Seismic velocities – P & S. Relationship to elastic moduli. Seismic anisotropy. . -- directional variation in seismic velocity. Seismic Attenuation – 1/. Q. p. & 1/Q. s. . -- What is seismic attenuation?. Lucy & Diana.
