Skin contamination by radioisotopes, (4). Pig skin contamination by ³⁵S, ¹²⁵Sb, ¹⁴⁷Pm, ²⁰⁴Tl and ²¹⁰Po

Experiments were carried out to determine the surface and interior contaminations in layers of fresh pig skin that had been soiled with ³⁵S, ¹²⁵Sb, ¹⁴⁷Pm, ²⁰⁴Tl, and ²¹⁰Po solutions of various acidities for various periods of soiling time. It was proved that Tl⁺ is cationic, S(SO₄^2-) is anionic and Sb³⁺, Pm³⁺, Po⁴⁺ are radiocolloidal in their mode and character of skin contaminability. The last three showed distinctive skin contaminations in the acidity regions for radiocolloidal formation. It was found that interior contamination is almost negligible, regardless of contaminant species, acidity, or soiling time. (author)
