Talk:Optically stimulated luminescence

QUESTIONS

How is optically stimulated luminescence used to date sediments?

I read the following on the BBC news website, concerning the dating of the human footprints in the Americas (article Footprints of 'first Americans' by Paul Rincon - link http://news.bbc.co.uk/1/hi/sci/tech/4650307.stm).

The researchers used radiocarbon dating on shells and animal bones in the sequences and dated mammoth teeth by a technique called electron spin resonance. The sediments themselves were dated by optically stimulated luminescence.

Is the OSL in fact a kind of photoluminescence ? It seems the OSL is a photoluminescence with the traps generated by the radiation ? Pls explain. — Preceding unsigned comment added by 87.164.133.69 (talk) 13:47, 21 August 2013 (UTC)

Where's difference?

Between this article and this: http://en.wikipedia.org/wiki/Optical_dating Maybe you should unite them? 62.140.253.6 (talk) 09:08, 6 April 2010 (UTC)

The difference is OSLs are used to measure radiation doses. Is it similar to the thermoluminescent film badges. Optical dating is a method which can use optically stimulated luminescence to date materials by looking at the total dose and then dividing it by the radiation dose rate. — Preceding unsigned comment added by 68.226.142.49 (talk) 07:38, 11 September 2013 (UTC)

Radioactive radiation

"ionizing radiation (commonly known as radioactive radiation)" Radioactive radiation? What a bizarre phrase, is this commonly used? Is it ever used? Mtpaley (talk) 13:56, 31 October 2010 (UTC)

I've deleted that - seems redundant to me.— Wdfarmer (talk) 08:38, 30 January 2011 (UTC)

References?

What are this for references? The first one can not be read, because you first need to register yourself and the second one can not be read because the link is dead. Are there any better references? — Preceding unsigned comment added by 134.76.124.179 (talk) 15:41, 1 November 2013 (UTC)
