Crepeele locale Radiocarbon Dates. C14 report by IsoTrace Laboratory for Crepeele site 2005 XU 8.
From 2003 to 2008 field work took place at the Crepeele locale with 75 - 1m x1m units excavated.
To help establish the cultural sequence at the locale Radiocarbon dates were obtained from the three sites in the Crepeele locale.
Radiocarbon dating
The technique of radiocarbon dating was developed by Willard Libby and his colleagues at the University of Chicago in 1949.
Radiocarbon dating is used to estimate the age of organic remains from archaeological sites. Organic matter has a radioactive form of carbon (C14) that begins to decay upon death. C14 decays at a steady, known rate of a half life of 5,730 years. The technique is useful for material up to 50,000 years. Fluctuations of C14 in the atmosphere can affect results so dates are calibrated against dendrochronology. Radiocarbon dates are calibrated to calendar years.
Dates are reported in radiocarbon years or Before Present. Before Present refers to dates before 1950. The introduction of massive amounts of C14, due to atomic bomb and surface testing of atomic weapons, has widely increased the standard deviation on all dates after A.D. 1700 causing these dates to be unreliable.
Accelerated mass spectrometry can more accurately measure C14 with smaller samples and can date materials to 80,000 years.
Scope and Content
Sub sub series contains radiocarbon dates from: Crepeele, Sarah and Graham sites.

Following the Second World War, Canada assisted with the resettlement of Europe's homeless. Orders in Council were passed between July 1947 and October 1948 that permitted the entry of 45,000 "displaced persons," who were referred to as "New Canadians" upon their arrival.

After the cancellation of McGuinness’ CBC Radio broadcast “Neighborly News from the Prairies” that he hosted from 1980 to 1983, McGuinness continued working with the CBC. He was popularly known for his work as the prairie essayist for CBC Radio’s Morningside with Peter Gzowski, a position he held for 17 years.

Photograph shows Fred McGuinness (left) and Peter Gzowki (right) having coffee in a restaurant.
Notes
Writing on the back of the postcard reads: Baron! Dear Fred - okay, okay so the photos aren't great...these are your copies anyways! How you are well - Love Shelley (the Countess)

According to the Canadian Old-time Radio Alliance website, the Happy Gang radio show was established by Bert Pearl for the CBC in 1937. The show remained on the air until 1959. Colgate Palmolive was the radio show's first sponsor. Other sponsors included Carnation Milk, Mills' Flower, and Red Rose.
