Mitigating radiation-induced toxicity: an overview of new approaches developed at the French Military Biomedical Research Institute.

abstract：:Spot urine samples are often taken for emergency radiobioassay to provide a quick dose assessment for contaminated individuals. The subsequent dosimetric analysis requires a urinary output normalization method to adjust spot sampling to daily urine excretion. A rapid specific gravity method that was developed for 24-h...
