Complementary Pu Resuspension Study at Palomares, Spain

The Environmental Effect of Radioactive Particles in the Contaminated Sites with Resuspended Plutonium Aerosols

“…It is clear that after the cleanup the contaminated particulates deposited in soil decreased remarkably and the resuspended concentration in air reduced four to five orders-of-magnitude. The comparison between the investigations of Iranzo [17] and Shinn [18] shows that the plutonium contamination deposited in soil and resuspended in air both reduced one further order-of-magnitude during ten years. Shinn figured out that the changes were derived from the combination of the field cultivation, the roads paving and the monsoon eroding.…”

“…During the soil cleanup soon after the accident it is appalling to find that the radioactive activity per unit area of surface soil D reaches 1.18 MBq/m 2 in the local heavily-contaminated areas [17]. In 1993 Shinn group of Livemore took over the monitoring facilities from Spanish government and the resuspended plutonium contamination in this site about 30 years after the soil cleanup was investigated systematically [18]. First of all Shinn group measured the daily variation of plutonium concentrations in Plot 2-1 (heavily contaminated area which is 1.5 km from the detonation point) and the mass loading of plutonium aerosols M suspended over the 24-hour period was obtained as shown in Fig.…”

The Hazard Analysis of Plutonium Aerosol Resuspension in Typical Dated Nuclear-Polluted Regions

“…From 1966 to 1982 Iranzo C E et al of CIEMAT measured the plutonium aerosol concentration of contaminated soil and air in Palomares [14][15][16] . Shinn J H et al of Livemore also investigated the resuspended contamination of this area in 1993 [17] . Fig.…”
