Calculate the area that, in theory, could be made uninhabitable (with a cumulative dose >250 mSv, unshielded stay over 50 years) from an emission where 1% of the Cs-137 inventory and 1% of the Cs-134 inventory from a light water reactor (1000 MWe) is released. Neglect noble gas contribution, neglect penetration of the coating by the ground. Assume that the short-lived radionuclides together contribute an external dose corresponding to 20% of the contribution from Cs-137 over a 5-year period.
