Procedures that the Fukushima nuclear plant workers would be following to deal with high R=radiation dose rates (like the high readings of 40 REM/hr) – move to an area with a lower dose rate. Radiation dose rates obey physical laws – if you double your distance from the source, you reduce the rate by a factor of four. If you reduce your time in the area with a high dose rate, you reduce your total dose proportionally.
If you put some shielding between you and the source of radiation, you can drop your dose even more quickly – 2 inches of lead, or 4 inches of steel or 24 inches of water will drop it by a factor of 10.
