Doctors also have found that the rays can penetrate living tissues for short distances and affect the tissue cells. Archives An Archive is the place where historical or government documents are stored. Carbon 14 has a half life of 5, years. Formation of varves depends on climatic variation.
Stratigraphy - Stratigraphy is the analysis of a series of layers that exist in the horizontal dimension, studied in the vertical time dimension.
ARCHAEOLOGY, TOOLS, METHODS AND ANALYSIS
When an organism dies, it contains a ratio of carbon 14 to carbon How they have new, almost forensic-like science to collect pollen and understand the vegetation. The ultimate cause of carbon variations with time is generally attributed to temporal fluctuations in the cosmic rays that bombard the upper atmosphere and create terrestrial carbon This determined by the position of excavated objects compared to other objects and the remains of buildings and other structures.

These include the major elements that make up our bodies. It is the duty of an archaeologist to study with care the condition of preservation of specimens submitted for analysis and, in fact, to submit only specimens that can be regarded as fool-proof as is possible in the circumstances.
The method is actually devised to measure the amount of low level radioactivity of carbon remaining in ancient and dead material of organic origin.
