not represent all of the radioactive material
that fell on these surfaces. In fact, data from
Table 21 suggests a relatively high ratio of
activity associated with thefiltrate. However,
it is probable that much of the insoluble material had settled out, therefore, the values do
solubility.
Tables 18,* 21,? and 22 ? show additional data
on gross activity found in water sources. Table
23 gives the analyses by HASL.®
other fallouts suggest a value of about 10-20%
