Calculations are presented for natural γ-ray spectra in equilibrium inside homogeneous,
infinite soils. The influences of moisture and nature of soils are investigated. The ratio of the …

Abstract Two portable NaI (Tl) spectrometers with four energy windows were used for the
recording of gamma-ray counts over soil and rock of differing natural radioactivity. The …

The use of a vertically mounted Ge (Li)-detector for gamma spectrometric measurements in
the field is described in detail. During measurement the portable detector assembly is …

The use of in situ gamma spectrometry to monitor environmental contamination by artificial
radionuclides has been examined. In particular, all sources of random and systematic …

The theoretical basis for gamma densitometry of soil by transmission is reviewed. It is
stressed that the familiar exponential‐inverse square law applies only to primary radiation …

A method is proposed to determine the activities of natural and artificial gamma-emitting
radionuclides in soils using in situ spectrometry that is validated with conventional low …

The algorithm used to calculate a minimum detectable activity (AD) of an environmental
volume sample measured by γ-ray spectrometry was modified and adapted for in situ …

Experimental and/or theoretical estimates are presented concerning (i) attenuation within
the sample of beta and gamma radiation from the soil,(ii) the gamma dose within the sample …

Portable gamma spectrometers have been used extensively to determine exposure rates
due to specific radionuclides in the earth's surface (Beck, etal., 1964, 1966, 1971; Cardinale …
