Laboratory Detection Limits

Description

Analytical method detection limits of selected radionuclides based on laboratory procedures.

Usage

dl

Format

A data frame with columns:

parm_nm

Long parameter name, such as "Strontium-90, water, unfiltered, picocuries per liter".

pcode

U.S. Geological Survey 5-digit parameter code used to identify the constituent measured, see parameters dataset for details. For example, the parameter code for Tritium is "07000".

lab_det_lim_va

Laboratory detection limit concentration.

min_dt

Date that the detection limit went into effect.
