A tumor is treated using an AP field with a high-energy photon beam. The tumor is located at a depth of 6 cm where the percent depth dose is 78.4%. The spinal cord is in the path of the beam and Is located at a depth of 14 cm where the percent depth dose is 35.3%. If 200 cGy is delivered to the tumor, calculate the dose delivered to the spinal cord.
