Abstract
PARCHOMENKO1 demonstrated that, when mixing silica gels with electrolytes of some metals such as magnesium, manganese, cobalt and nickel (with iron always present) by precipitating their chlorides with sodium silicate, compounds can be prepared which are highly absorbent for radioactive salts, and owing to their large colloidal surface give off radon nearly quantitatively.
