Reverse dosimetry definition
Probabilistic Reverse dOsimetry Estimating Exposure Distribution (PROcEED) What is PROcEED? PROcEED is a Webbased application used to perform probabilistic reverse dosimetry calculations for estimating a distribution of exposure concentrations likely to have produced biomarker concentrations measured in a population.Reverse dosimetry uses a pharmacokinetic model along with measured biomarker concentrations to determine the plausible exposure concentrations a critical step to incorporate groundtruthing experimental data into a distribution of probable exposures reverse dosimetry definition
Apr 26, 2008 Reverse dosimetry. The fundamental problem underlying reverse dosimetry is to relate a measured internal dose, or tissue concentration, C T, to an unmeasured external exposure or dose, C D, given a deterministic model f (we consider f to be minimally a PBPK model).
Reverse dosimetry definition free
Probabilistic reverse dosimetry accounts for uncertainty and interindividual variability in exposure patterns and pharmacokinetics to estimate a distribution of exposure concentrations likely to have produced the observed biomarker concentrations in a population. Monte Carlo analysis is a common tool for generating the probabilistic distributions of the dosebiomarker relationship.

dosimetry dosimetry ( dosimtre ) scientific determination of amount, rate, and distribution of radiation emitted from a source of ionizing radiation, in biological d. measuring the radiationinduced changes in a body or organism, and in physical d. measuring the levels of
Radiation dosimetry in the fields of health physics and radiation protection is the measurement, calculation and assessment of the ionizing radiation dose absorbed by an object, usually the human body. This applies both internally, due to ingested or inhaled radioactive substances, or externally due to irradiation by sources of radiation.
