In a follow up to their earlier May report, the Lithuanian Academy of Science summarizes levels of radiation detected between April and August of 1986 following the Chernobyl nuclear accident. Atmospheric tests showed a sharp rise in radiation levels in late April, up to 50 times higher than Soviet standards for safe levels of exposure. Levels dropped off in May, with occasional spikes. The report also summarizes tests of food products grown in Lithuania or imported from other Soviet Republics.
