natural radionuclides present in soil as well as certain anthropogenic radionuclides released to the environment are the major contributors to terrestrial outdoor exposures. in the assessment of human exposures from environmental radioactivity, besides the conventional method of soil and vegetation sampling combined with laboratory based analyses of environmental media, the other choice would b...

local site conditions have a strong effect on ground response during earthquakes. two important soil parameters that control the amplification effects of seismic motions by a soil column are the soil hysteretic damping ratio and shear wave velocity. this paper presents the results of in situ damping ratio measurements performed using continuous surface wave attenuation data at a site in semnan ...

Measurements made in situ with gamma detectors and ex situ measurements of soil samples in a laboratory can have complementary roles in the assessment of radioactively contaminated land on decommissioning nuclear sites. Both in situ and ex situ methods were used to characterize (137)Cs contamination within an area at the Dounreay site in Scotland. The systematic difference (bias) between estima...

This study was conducted to determine the chemical composition, digestibility, degradability and nutritive value of madder, Rubia tinctorum L.  and alfalfa Medicago sativa. using in vitro and in situ measurements. The mean values for OM, CP, NDF, ADF and EE were 892.5, 172.0, 306.5, 219.4 and 16.0 g/kg DM for madder hay, and 921.3, 141.4, 482.0, 361.1 and 6.50 g/kg DM for alfalfa hay, respectiv...
