Information on how to conduct exceptional exposure assessments has grown exponentially over the past 15 years. The availability of inexpensive computational approaches and advanced modeling, as well as super sensitive analytical techniques allows scientists to characterize the range of possible exposures with increasing precision. In many ways, ChemRisk^® pioneered the use of many of these methods.

Intimately related to our experience in exposure assessment is our knowledge of dose reconstruction techniques. Dating back to the early 1980s, we were conducting some of the first studies where the exposure of workers and citizens was reconstructed using historical industrial hygiene and work records, as well as corporate and industry documents. We have conducted more than $40,000,000 in dose reconstruction studies for the government and as many as a dozen studies of various workplaces.
