More general recommendations are as follows: 1. As time permits, factors should be examined wnich contribute to biasing the INP and/or soil sample results. 2. The surface soil activity relating to the cleanup criteria should be more clearly defined. Are we talking about activity per gram of dry soil, less than a certain particle size, containing no rocks, averaged over the top 3 cm? Or are we talking about activity per gram of in-situ material averaged over the area and depth of whatever the IMP sees? 3. If the definition relates more closely to the soil samples, then it is recommended that all the IMP measurements be multiplied by an imperically determined correction factor according to Table 1, providing that factors leading to biasing in the soil sample results have been examined and resolved. 4. If the definition relates more closely to the IMP readings, then it is recommended that no corrections be made unless biasing of greater than 10% in one direction has been verified.
