Soft γ radiation which produces rather high background rates in unshielded scintillation counters has been studied; it is concluded that near surface of earth, radiation is primarily from earth and building materials; at high aircraft altitudes it is primarily due to degraded cosmic radiation and at lower altitudes it is due to air radioactivity and cosmic radiation.
