A study of worker dose distributions with respect to ICRP dose limitation recommendations.

abstract：:Due to their high stability and accumulation over time, translocations are currently the cytogenetic marker of choice for radiation dose estimation following protracted radiation overexposures or overexposures that occurred up to several decades in the past (environmental/occupational/medical exposures). In the course...
