Advertisements VII • The claims made for the prodnction of irradiated vitamin D milk in the "National” Type YN Milk Irradiator at the time of its introduction a little more than two years ago have been more than fulfilled. Introductory advertising on this unit claimed a capacity o f4,000 pounds per hour o f400 U.S.P. unit muk. Reports received from milk plants operating YN units showed that actual operating schedules were much higher than this figure. Conservative capacities established by the experi­ ences of the industry itself now show that the "N a­ tional” YN unit irradiates fluid milk at the rate of 8,000-10,000 pounds per hour at a 400 U.S.P. unit potency. Despite this increase in production rate the design of the YN irradiator remains essentially the sa™-e today as it was when the unit was introduced. National Carbon Company, Inc. is proud of this record. , . tu rate of 17*500 !35 U.S.P. unit mi'k “ Q^ ePrndUintensity of radiation can at ,he p ..ate of adjacent milk processing equipment.
