The report evaluates firehosing as a wet reclamation procedure for the operational recovery of asphalt paved streets contaminated with fallout from a land surface nuclear detonation. Preliminary tests with inert fallout simulant determined the optimum nozzle stream range and firehosing technique. Principal tests, conducted with radio-traced simulants, measured the effects of hosing rate, stream pattern, particle size and mass loading on the fallout removal performance of firehosing. Several conclusions were indicated 1 A slow hosing rate visually controlled was more effective than a faster rate, regardless of mass loading or particle size range. 2 The removal effectiveness improved with increased particle size range and increased mass loading. 3 An experimental NRDL flare nozzle appeared to improve hosing performance at nozzle pressures greater than 150 psi. Graphs showing the effect of hosing rate, particle size, mass loading and stream pattern on the reclamation performance of firehosing are presented.
