Note that this is a drug for treating acute radiation syndrome. This would have been relevant for Chernobyl because they had firefighters working right up against the exposed core trying to put out the fire in the graphite and getting lethal doses of radiation.
In Fukushima it's not relevant as they're taking care not to expose people to more radiation than is easily survivable.
Very different level of emergency, there's currently nothing in Fukushima to warrant risking lives.
Reductionist and proud of it.
