The radir package for R was written to provide a tool for radiation dose estimation, based on chromosome aberration and calibration curve data. The tool takes a Bayesian approach, providing the results in the form of a posterior 'Calibrative Density' of dose, and thus probabilities - for instance for likelihood of dose < 1 Gy - can be easily extracted.

How to obtain the software

The package is available for download from
