Calculate a decay constant

Description

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).

Usage

pb210_decay_constant(half_life = set_errors(22.2, 0.22))

Arguments

half_life

A half-life value (in years).
