“…Analyses of 226 Ra concentration from samples of those plants showed concentrations varying from 96 to 7,990 mBq kg -1 in dry matter (Silva et al 2004). Part of the 226 Ra ingested from the forage by a dairy cow is transferred to the milk (Watson et al 1984). For dairy cattle raising and milk producing rural region of Pernambuco, the extensive and semi-intensive management systems practiced by 75% of the producers is predominant, 50% of the native pasture is the principal source of feeding (SEBRAE 2002).…”

This work is aimed at determining (226)Ra concentration in cheese produced by dairy manufacturers from Pedra and Venturosa, which are two districts in the rural region of Pernambuco-Brazil. Analyses showed concentrations of (226)Ra in cheese samples varying from 54 to 2,080 mBq kg(-1) (wet matter). Using the cumulated risk method, the excess carcinoma and bone sarcoma were estimated for chronic ingestion of cheese containing this radioisotope. In this context, this report discusses the methodology of sample analyses as well as possible consequences of the (226)Ra intake for human health.
