The Wethersfield (1982) chondrite was assayed for a suite of cosmogenic radionuclides shortly after fall. Data are reported for 7 Be, 22 Na, 26 Al, 46 Sc, 48 V, 51 Cr, 54 Mn, 56 Co, 57 Co, and 60 Co. A comparison is made with predicted results based on a scaling to the Deep River Neutron Monitor. Noble gases were also assayed in a sub‐sample. The cosmic ray exposure age is estimated to be 45 million years.
