N O T E S | ||||
Depending on degree of exposure, estimation of dose received may be required by whole body counting technics.
Depending on the degree of exposure, periodic medical examination is indicated.
This material and its decay products are radioactive. Storage in a poorly ventilated area may result in a buildup of gaseous radioactive decay products.
Prolonged retention in the body leads to long term alpha-irradiation of the tissues. May result in changes in the blood-forming, nervous and reticulo-endothelial systems, and functional and morphological damage to lung and bone.
Do NOT take work clothing homewards.
