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).
本研究的目的是测定在巴西伯南布哥州首府累西腓市供人类消费的甘蔗汁样品中的镭-226浓度。样品采集在17个通常大量销售甘蔗汁的商业场所进行。用于测定甘蔗汁中镭-226浓度的方法基于氡-222发射经典技术。样品中镭-226的浓度在18至89毫贝克勒尔每升之间变化。
