Physical Dosimetric Reconstruction of a Radiological Accident at Nanjing (China) for Clinical Treatment Using Thudose.

abstract：:Because of fast growing medical radiation use, estimating possible late health effects of radiation, including potential cancer risk, is an issue of substantial interest. Since physicians make the decision to order or perform a radiological procedure, it is very important to provide them with objective information abo...
