The objective of this study was to determine the 226Ra concentrations in samples of sugar cane juice, which is sold for human consumption in the city of Recife, capital of the state of Pernambuco, Brazil. The sample collections were carried out in seventeen commercial establishments where high quantities of the juice are usually sold. The methodology used to determine the concentrations of 226Ra in the juice was based on 222Rn emanation classical technique. Concentrations of 226Ra in the samples varied from 18 to 89 mBqL(-1).
