The survey of a luminous dial painting plant is described. Under the conditions investigated, skin contamination was indicated as a major mode of entry of tritium into the body of the workers. A new unit, gram-Lambert (g-L) is proposed for comparison of radioactive luminous paints. It is shown that the benefit of the production of 1 g-pL is associated with the risk of approximately 0.16 mrem to the workers studied. A maximum tritium activity which may be processed by a worker without exceeding the maximum permissible body burden is proposed.
