thick steel blast doors. An example of privately funded fallout shelters is the Ark Two Shelter in Ontario, Canada, and autonomous shelters have been constructed with an emphasis on post-war networking and reconstruction. In Switzerland, the majority of homes have an underground blast and fallout shelter. The country has an overcapacity of such shelters and can accommodate slightly more than the nation's population size. While the nuclear fallout shelters described above are the ideal long-term protection methods against dangerous radiation exposure in the event of a nuclear catastrophe, it is also necessary to have mobile protection equipment for medical and security personnel to safely assist in containment, evacuation, and many other necessary public safety objectives which ensue as a result of nuclear detonation. There are many basic shielding strategies used to protect against the deposition of radioactive material from external radiation environments. Respirators that protect against internal deposition are used to prevent the inhalation and ingestion of radioactive material and dermal protective equipment which is used to protect against the deposition of material on external structures like skin, hair, and clothing. While these protection strategies do slightly reduce the exposure, they provide almost no protection from externally penetrating gamma radiation, which is the cause of acute radiation syndrome and can be extremely lethal in high dosages. Naturally, shielding the entire body from high-energy gamma radiation is optimal, but the required mass to provide adequate attenuation makes functional movement nearly impossible. Recent scientific studies have shown the feasibility of partial body shielding as a viable protection strategy against externally penetrating gamma radiation. The concept is based in providing sufficient attenuation to only the most radio-sensitive organs and tissues in efforts to defer the onset of acute radiation syndrome, the most immediate threat to humans from high doses of gamma radiation. Acute radiation syndrome is a result of irreversible bone marrow damage from high-energy radiation exposure. Due to the regenerative property of hematopoietic stem cells found in bone marrow, it is only necessary to protect enough bone marrow to repopulate the exposed areas of the body with the shielded supply. Because 50% of the body's supply of bone marrow is stored in the pelvic region which is also in close proximity to other radio-sensitive organs in the abdomen, the lower torso is a logical choice as the primary target for protection.
