From: Alteration of archeological and natural analogs for radioactive waste glass under different environmental conditions

Fig. 3

For sites with analogs from multiple time periods, a colored rectangle describes the minimum and maximum ages. The timeline is shown in years before present, with present defined as 2024. For nuclear waste disposal, glasses are assessed for a 1000-year compliance evaluation with additional analysis performed out to 10,000 years to determine peak elemental release31.
