Abstract
The present invention relates to a precast radiation protection board, which is structured for jointing another protection board. The protection board includes a protection layer that is formed of a mixture of barium sulfate and cement and outside isolation plates that are respectively attached to opposite sides of the protection layer. The outside isolation plates are fiber cement boards. This arrangement allows the precast structure to be efficiently installed and allows for direct painting or decorative coating, so as to significantly reduce operation time.
