<li class="annotation-item"><span>Radium-226</span> is often created during nuclear fission when Uranium-238 decays. In the early part of the century, it was used in glow-in-the-dark paints and luminescent gauges during World War II. On Treasure Island, ship repair and salvage yards, as well as an optical shop, are the main sources of exposure. It can be ingested or inhaled and accumulates in the bones. Though naturally present in the environment, long-term high exposure can lead to blood, lymph and bone cancers. It takes about 1,600 years for radium-226 to decay into Radon, which is chemically stable.</li>
<li class="annotation-item">Cesium-137</span> is most often produced as a byproduct of nuclear fission in reactors and weapons. It has a half-life of about 30 years. Ships undergoing atomic bomb tests in the 1950s may have absorbed the radioactive isotope. It can be ingested or inhaled and is now present at low concentrations throughout the world. Long-term exposure increases cancer risk, and high levels can lead to burns and death. On Treasure Island, sealed cesium-137 sources were used to simulate nuclear fallout.</li>

At the top of the page there are six buttons. Each button turns on or off a layer. For example, if you don't want to see the plans for new housing units, click Redevelopment Sites to hide it. As you hover over the circles or radioactive markers, this window will update with facts about that site. Or, <a href="#" id="proceed-0" class="proceed">start the tour for more background</a>.

With plans to redevelop the Treasure Island by adding new housing – enough for 20,000 people – The Navy will turn over to San Francisco a former Naval Station that was once site of a school training sailors in nuclear war. Originally, The Navy identified one site at the corner of Avenue M and Fifth Street as contaminated.

The California Department of Public Health surveyed the northeastern section of the island in April 2011 for radiation. They found 89 locations where the radiation was double normal exposure rates.
<br/><br/>It identified four locations where, if you sat there for one year, you would be exposed to what California defines for civilians as unsafe levels of radiation: more than 100 millirems per year.
<br/><br/>For example, someone living in or around San Francisco is exposed to 44 millirems of radiation per year on average, according to a report from the Lawrence Livermore National Laboratory. Your home, by contrast, emits 200 millrems of radiation annually on average, according to the Environmental Protection Agency.
<br/><br/>At one of these four locations, you could be exposed to as much as 4,380,000 millirems of radiation if you spent all year there.

At the California Department of Public Health's insistence The Navy conducted a second, more detailed survey after it was determined the original reports failed to capture the scope of the potential contamination.
<br/><br/>In it, several new sites were identified as potentially radiated based on the site's history. Without further testing, it's not known whether these sites -- one of which now has a day care and elementary school on its premise -- are dangerously radioactive.
