Description: Moisture measurements were made in three media–paraffin, water, saturated sand–with four neutron miusture meters, each containing 226-radium-beryllium, 227-actinium-beryllium, 238-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: soil moisture measurement; neutron moisture meter soil moisture meter; soil surface moisture; vertical resolution; americium-beryllium; hydrometeorology
