132. brazil nuts
Incidentally, Brazil nuts are over 1000 times more radioactive than other foods because of their high radium content.

Anybody spread fertilizer around their garden? One kg of fertilizer emits over 5,000 Bequerel (disintegrations/sec) of radiation due to Potassium-40. Compare to some other common, radioactive substances:

Human beings: 100 Bq/kg
Bananas: 130 Bq/kg
Brazil nuts: 207 Bq/kg
Granite kitchen countertop: 1000 Bq/k
