SOIL WATER MEASUREMENT WITH AN AMERICIUM 241-BERYLLIUM NEUTRON SOURCE AND AN APPLICATION TO EVAPORIMETRY

THE USE OF A 150MC AMERICIUM 241-BERYLLIUM SOURCE IN AN OTHERWISE STANDARD NEUTRON SOIL WATER CONTENT PROBE GAVE SEVERAL SIGNIFICANT ADVANTAGES. THESE WERE ELIMINATION OF GAMMA RADIATION AND ATTENDANT HEALTH HAZARD, REDUCTION IN WEIGHT, INCREASED COUNTING RATE, AND AN APPARENTLY INCREASED DEPTH RESOLUTION. SOIL WATER INVENTORIES AT ONE SITE TO A DEPTH OF 170 CM COULD BE OBTAINED WITH A PRECISION OF AROUND 0.1 CM OF WATER. A SUGGESTION IS MADE THAT IMPROVED NEUTRON LOGGING BE COMBINED WITH A SUCTION-TYPE PERCOLATION LYSIMETER TO OBTAIN SHORT-TERM AMOUNTS OF EVAPORATION WITHOUT A WEIGHING MECHANISM. /AUTHOR/
