Samples of quartz, microcline, and albite in five silt-size ranges were annealed at 250[degrees]C and then dosed with 2, 4, 8, 16, and 32 mrads of radiation from a Cobalt-60 source (total samples).
What's more, data available from Mitsui Plastics, Inc., White Plains, N.Y., shows less yellowing of both stabilized and unstabilized forms of Mitsui's TPX polymethylpentene resin from exposure to 5 megarads of electron-beam radiation than from 5 Mrads of gamma exposure.
