Description: "Abstract - Moisture measurements were made in three media--paraffin, water, saturated sand--with four neutron moisture meters, each containing 226-radium-beryllium, 227-actinium-beryllium, 239-plutonium-beryllium, or 241-americium-beryllium neutron sources. Variability in surface detection by the different sources may be due to differences in neutron sources, in length of source, or both."

Keywords: "PSW4351, soil moisture measurement, neutron moisture meter, soil moisture meter, soil surface moisture, vertical resolution, americium-beryllium, hydrometeorology"
