Such materials are considered to have no rad added if the alpha is below 15 <br /> pCi/g soil and the beta is below 25 pCi/g soil and tritium below 5 pCi/g of soil.For samples <br /> that are below the above alpha and beta limits but have tritium values greater than 5 but less <br /> than 60 pCi/g of soil, the soil cannot be landfilled but may be stored on site.For soils that <br /> exceed these limits of gross alpha or beta or exceed 60 pCi/g of soil of tritium activity, the <br /> soil should be treated as radioactive waste." <br /> (Rev. 2.1,March 11, 1994) EAS (510)424-4127 <br />
