The original Hybrid Assistive Limb (HAL) suit was designed to help those with muscle diseases, but it's now been upgraded to cope with a very different type of problem: handling radioactive substances. One of the few wearable materials that can stop radiation is tungsten, which is extremely heavy: a typical tungsten vest weigh up to 132 pounds. When worn in conjunction with a HAL exoskeleton, however, a vest can be worn for lengthy periods without causing fatigue -- potentially allowing greater access to hazardous sites like Fukushima.
