Wouldn't that just mean that the detector needs to be increasingly sensitive to detect a late-1940's forgery?

- rtkwe 1y agoYou should also be able to use the presence of the decay daughters as another way to detect forgeries.
- philipkglass 1y agoCesium 137 decays to barium 137 which is stable and naturally occurring, so the cesium daughter wouldn't be useful for this case (non-destructive testing of sealed wine bottles).
