The maximum amount of material used per day based on an operator painting clock dials of the largest size which required the greatest amount of material, would be 10 grams. An average amount used would be spproximately 6 grams. 3. The radium content of grade G msterial is 2.66 mgs. per 100 grans. 4. The number of persons engaged at one time was variable. We have had anywheres from a dozen to over 200. 5. The application operated thruout the year more or less. Usually more work was done during the fall of the year. 6. Our operators changed often. To determine an average time would be difficult without considerable time being spent on all the payrolls and checking esch employee.
