13577 Radiation Film Badges were used at Hunters Point Shipyard in 1960

In 1960 the US Naval Radiological Defense Lab developed 2655 Radiation Measuring Film Badges for Treasure Island and 12,688 for the US Naval Radiological Defense Lab at Hunters Point Shipyard along with 889 for Hunters Point Shipyard separate from the Defense Lab. These badges are dosimeters that measure how much radiation a person was exposed to during a period of time and they were collected from all over the Bay Area to be developed and analyzed at the Defense Lab for the year of 1960.

This document is a who’s who of radiological exposure just for one year at the US Navy’s Radiological Defense Laboratory and I highly recommend it as reading material to give you a look into the radiation experiments they conducted on the shipyard (including building numbers) and all throughout the Bay Area, including downtown San Francisco!

The presence of radiation badges means each time a human being was exposed to radiation over the course of an experiment or regular monitoring of radiation exposure on site. A very frequent and robust radiological contaminations were taking place at the Shipyard and Treasure Island in 1960.

Camp Parks in Dublin CA was the field station for the Lab where they conducted radiological tests on the base while military personnel worked and lived on the base. These experiments included using the gymnasium to rain down radioactive isotopes to determine its effects on roof structures and that gymnasium was then “cleaned up” and was used by the Navy and then the Air Force when they took over the base and as recently as last year by private entities before it was torn down. Stanford Research did a lot of radiological work at Camp Parks and it is clear they had many nuclear accidents reported in this report from 1960.
