Q:
Why is it so important to measure chlorine content?
A: Chlorine exerts
a systematic control on fission track annealing (the rate at which
tracks shorten in response to heating), and different grains within
a sample can show significant differences in the degree of annealing.
Measuring wt% Cl allows us to include this differential annealing
as an additional parameter to constrain thermal history, whereas
ignoring the effect can lead to major errors. Find
