Arguments

activity	A vector of measured lead-210 specific activities (in Bq/kg) and associated error. These can have errors::errors().
background	A vector of estimated background lead-210 specific activity (in Bq/kg) and associated error. These can have errors::errors().

Value

Examples

core <- pb210_simulate_core(depth_step = rep(1, 30)) %>%
  pb210_simulate_counting()

pb210_excess(
  set_errors(
    core$activity_estimate,
    core$activity_se
  ),
  background = 10
)
