Seaweed mass production device using ionizing radiation

A seaweed mass production device using ionizing radiation consists of: a housing unit having a placing area and a filter; a cubic frame positioned in the housing unit, an attachment unit surrounding the cubic frame; and an irradiation unit of radiation positioned at one side of the housing unit. Production procedures includes: injecting cultivating liquid into the housing unit; planting a plurality of seaweed spores on the attachment unit; using filter to help cultivate the seaweed by flowing the liquid and using the irradiation unit of radiation to perform irradiation of desired dose; after the spore grows and become seaweed seedling, taking off the attachment unit and placing it inside outdoor flowing pond for re-cultivation until each seaweed grows a certain length ready to be picked. Thus, it is able to agitate growth by using radiation hormesis method in order to increase its width and shorten its growth period so as to obtain mass production of seaweed.
