Optically stimulated luminescence (OSL) dating is now widely used by Quaternary scientists; it can provide ages in a range well beyond that of radiocarbon and on deposits from environments not conducive to the preservation of organic matter.

What is optically stimulated luminescence in Archaeology?

Optically-Stimulated Luminescence is a late Quaternary dating technique used to date the last time quartz sediment was exposed to light. Once this sediment is deposited and subsequently buried, it is removed from light and is exposed to low levels of natural radiation in the surrounding sediment.

What is the main advantage of thermoluminescent dosimeters over film badges?

The advantages of a TLD over other personnel monitors is its linearity of response to dose, its relative energy independence, and its sensitivity to low doses. It is also reusable, which is an advantage over film badges.

What does a dosimeter measure?

What does the dosimeter do? A radiation dosimeter or badge does not provide protection but detects and measures radiation that you have been exposed to. The badge will detect high-energy beta, gamma or x-ray radiation.

What are the 4 ways to protect yourself from radioactivity?

In the event that you are faced with danger from gamma radiation or ionized particles in the air, the basic principles to remember for radiation protection are time, distance, and shielding.

How do thermoluminescent dosimeters work?

A thermoluminescent dosimeter, or TLD, is a type of radiation dosimeter, consisting of a piece of a thermoluminescent crystalline material inside a radiolucent package. When a thermoluminescent crystal is exposed to ionizing radiation, it absorbs and traps some of the energy of the radiation in its crystal lattice.
