Description

A data set containing some decay constants regular used in earth science and geochronology.

Usage

decayConstants

Format

A data frame with 6 rows and the following 5 columns:

1. name of the radioactive isotope – element symbol and mass number

2. value it's value and

3. err uncertainty as given by the reference. Uncertainty may be NA if not stated.

4. unit of the decay – usually per year (y), in some cases per day (d)

5. refkey key to reference. Also makes the entry in this table unique if there is more than one decay constant per isotope

The following decay constants are included:

• Ar37

• Ar39

• K40

• Rb87
  

Some of them are included more than once in this table because their values changed over time.
