The most commonly cited half-life for lead-210 is 22.26 with 2-sigma uncertainty of 0.22 (Hohndorf 1969), however Holden (1990) recommended using a value of 22.6(1). Most recently, Basunia (2014) recommended using a value of 22.20 with Hohndorf's (1969) uncertainty of 0.22 years. Sanchez-Cabeza et al. (2014) use the half life and uncertainty reported by Chiste and Be (2007) of 22.23(15). The default value is the most recently reccomended value (Basunia 2014).
