 It has been suggested that chelation agents such as British Anti-Lewisite (dimercaprol) can be used to decontaminate humans. In one experiment, rats were given a fatal dose of 1.45 MBq / kg (8.7 ng / kg) of 210Po; all untreated rats were dead after 44 days, but 90 % of the rats treated with the chelation agent HOEtTTC remained alive after 5 months.
