Abstract Difficulties in evaluating accurate equivalent doses for Late Quaternary sediments from the south coasts of Greece arose in the course of SAR measurements. Large scatter among apparent equivalent doses perplexed the evaluation of accurate mean estimates in circumstances where very large doses were involved. Besides, dose recovery experiments revealed that when intersection of the natural signal occurs onto the saturating segment of the growth curve, a distinct relationship between De and growth curve shape occurs. At very low slope angles, SAR tends to overestimate the recovered dose. The mechanism which controls the spread in equivalent dose estimation is investigated.

Purpose: To estimate the doses to a surgeon for a new operation – radionuclide vertebroplasty. To normalize the irradiation for the maximum number of operations in which the total equivalent dose will not exceed the values specified in the NRB-99/2009. Material and methods: The widespread Monte-Carlo code MCNP used with data libraries, as well as the ICRP-38 data on radionuclide characteristics. Results: Using the radionuclide 188Re, the most promising for this procedure, the equivalent dose in the doctor’s palms does not exceed 1 mSv per operation. A surgeon can perform up to 580 operations per year without violating radiation safety standards. Conclusion: Calculation methods proved the safety of radionuclide vertebroplasty for the surgeon and service personnel.

The benchmark dose (BMD) methodology is used to derive a hazard characterization measure for risk assessment in toxicology or ecotoxicology. The present paper’s objective is to introduce the R extension package bmd, which facilitates the estimation of BMD and the benchmark dose lower limit for a wide range of dose-response models via the popular package drc. It allows using the most current statistical methods for BMD estimation, including model averaging. The package bmd can be used for BMD estimation for binomial, continuous, and count data in a simple set up or from complex hierarchical designs and is introduced using four examples. While there are other stand-alone software solutions available to estimate BMDs, the package bmd facilitates easy estimation within the established and flexible statistical environment R. It allows the rapid implementation of available, novel, and future statistical methods and the integration of other statistical analyses.
