Dose rate attenuation factors for Co-60 radiation were measured along the entranceway of the 100-man shelter at the U. S. Construction Battalion Center, Port Hueneme, California. These dose rates were compared with those calculated by a computer code and found to be within a factor of two agreement. An attempt was also made to measure the protection factor of the entire shelter proper. It was determined that the protection factor is about 200,000. Since the protection factor near the outlet of the entranceway is about 40,000, radiation streaming through the entranceway is seen to be important. Author
