Description

Calculate time for a radionuclide to decay to a target activity.

Usage

1
dk_activity(A0, half_life, target)

Arguments

A0

The original activity, or related parameter.

half_life,

Half-life. Units are arbitrary, but must match time past.

target

The target activity.

Value

time, in same units as half-life, to decay to target activity.

# How long does it take for original activity of 10000 Bq to decay to 2500 Bq 
# if half-life is 5 minutes? 
# (All time units are consistent, so answer will be in minutes)
dk_activity(A0 = 10000, half_life = 5, target = 2500)
