Abstract
ozone concentration in the Co-60 industrial irradiator is controlled by the local exhaust ventilation (LEV). if the event of a ventilation malfunction, the ozone concentration becomes increasingly sensible within the radiation chamber. Ozone (O3) is a toxic gas which can cause tract, asthma, and permanent lung damage. its detrimental effects on humans and corrosion of metal parts within the radiation chamber indicates its importance as a safety factor consideration. The motivation for this work designs a standby system to reduce the ozone concentration within the Co-60 industrial radiator. MATLAB was used to simulate the effect of ultraviolet (254 nm) absorption cells on ozone concentration and calculate the decay time. The simulation illustrated that UV absorption is linearly increasing with increasing ozone concentration. Employing a UV Cell proved to reduce ozone concentrations and their decay time with an efficiency of 99%. This may prevent or significantly reduce the discharge of ozone into the air from the workplace. so it’s recommended that’s using UV (254 nm) in the ozone concentration within the Co-60 industrial as it is cheap and efficient controlling substance.
