Can 36 Cl be used to date water in soil?

Thus, as an event marker of 1950s water in soil and ground water, 36 Cl is also useful for dating waters less than 50 years before the present. 36 Cl has seen use in other areas of the geological sciences, including dating ice and sediments. ^ a bAudi, G.; Kondev, F. G.; Wang, M.; Huang, W. J.; Naimi, S. (2017).

What is the concentration of chlorine 36 in the atmosphere?

Chlorine-36. This corresponds to a concentration of approximately 1 Bq/ (kg Cl). 36 Cl is produced in the atmosphere by spallation of 36Ar by interactions with cosmic ray protons. In the top meter of the lithosphere, 36 Cl is generated primarily by thermal neutron activation of 35 Cl and spallation of 39K and 40Ca.

Is 36Cl a stable isotope of chlorine?

Chlorine-36 (36Cl) is an isotope of chlorine. Chlorine has two stable isotopes and one radioactive isotope: the cosmogenic isotope 36Cl.

Is 36Cl the best way to date old groundwater?

subsurface processes is evaluated. Results from 36Cl dating of old groundw ater can now be compared with those from a variety of other methods for dating. These comparisons are generally internally consistent and support the widespread use of 36Cl for dating old groundw ater. References.

How much readily available water do I need for my crop?

The amount of Readily Available Water varies with soil type, crop, rooting depth and irrigation system. Follow these six steps to work out your crop’s RAW.

Is there a difference between 36Cl dating and organic Reservoir dating?

The residence times in the organic reservoir (plants plus soil) is almost certainly quite short compared to the residence time in aquifers being considered for 36Cl dating, but the retention will help to smooth short-term fluctuations in 36Cl and Cl deposition.
