Using the track micromapping technique the physical interaction - the
adherence - between the U in solutions and the materials of the soluti
on storage vessel walls was investigated. Our results on the U adheren
ce to different materials currently used to make the storage vessels s
uch as: ordinary glass, brown glass and polyethylene are presented. Th
e implication of the U adherence in the charge of its solution state a
s the producing of the pseudoradiocolloidal state is mentioned.
