IntCal04 terrestrial radiocarbon age calibration, 0-26 cal kyr BP [PDF]

, 2004
A new calibration curve for the conversion of radiocarbon ages to calibrated (cal) ages has been constructed and internationally ratified to replace ImCal98, which extended from 0-24 cal kyr BP (Before Present, 0 cal BP = AD 1950).

Study on a New Label Dosimeter for Radiation Processing

Journal of Isotopes, 2016
In order to monitor the absorbed dose of goods in 60Co γ-rays and electron beams, a new label dosimeter had been developed for dose measurements. The label dosimeter had a multilayer structure, and the core of which was a layer of radiochromic film.
