摘要：

Narrow-beam mass-attenuation coefficients were measured for air, neon, argon, krypton, and xenon. Radioisotope sources were used to provide photons whose energies were 4.508, 5.895, 9.243, 27.380, 44.229, 88.09, and 145.43 keV. Experimental errors were less than 2% for all measurements. The experimental results are compared with theoretical predictions of the attenuation coefficients.
