The blue-light stimulated luminescence ages using the most light sensitive component are shown to be in good agreement with the independent control, up to 500 ka.

My tongue, every atom of my blood, form'd from this soil, this air, Born here of parents born here from parents the same, and their parents the same, I, now thirty-seven years old in perfect health begin, Hoping to cease not till death.

Creeds and schools in abeyance, Retiring back a while sufficed at what they are, but never forgotten, I harbor for good or bad, I permit to speak at every hazard, Nature without check with original energy.

The silt size sample disks are normalized for sample homogeneity by a 5-second exposure to infrared illumination and detection of the resulting luminescence by a photomultiplier tube covered with Schott BG-39 and Kopp 7-59 filters, as well as a Pyrex window.

The is obtained by heating the disk to 500°C and the electronically intensified light emission is recorded as a function of the heating temperature.
