            Cybersecurity Modernization Initiative
                We are taking steps to continue to modernize and secure our data, applications, and systems. We completed the first phase and restored many of the functions put on pause in May 2021. Now that the first phase is complete, work will resume at a slower pace but will speed up as new systems and applications are brought online. For more information and updates, please visit our Cybersecurity Modernization Initiative web page.

(Site Profile/Docket Number 151)
Location: Chicago, Illinois
Also known as: Eckhardt Hall (+ West Stands, New Chem. Lab and Annex, Ryerson Physical Lab, Kent Chem. Lab), Met Lab
Special Exposure Cohort Petition Information
The Special Exposure Cohort (SEC) is a unique category of employees established by the Act (42 CFR Part 83). Claims compensated under the SEC do not have to go through the dose reconstruction process. To qualify for compensation under the SEC, a covered employee must meet specific requirements (e.g., must have at least one of 22 “specified cancers,” and have worked for a specified time period at one of the SEC sites). Classes of employees and work sites can be considered for addition to the SEC through a NIOSH petition process. More information about the Special Exposure Cohort can be found on our Frequently Asked Questions page.
Open/Active SEC Petitions
To date, there are no open/active SEC petitions from Metallurgical Laboratory.
Class(es) Added to the SEC
All AWE employees who worked at the Metallurgical Laboratory in Chicago, Illinois, from August 13, 1942 through June 30, 1946, for a number of work days aggregating at least 250 work days, occurring either solely under this employment or in combination with work days within the parameters established for one or more other classes of employees in the SEC.

NIOSH is committed to applying the best available science in dose reconstructions. In keeping with this commitment, completed cases with probabilities of causation less than 50% are reviewed as relevant new information becomes available. The results of these reviews are described in a Program Evaluation Report (PER). The PER details the effect, if any, of the new information on the completed dose reconstruction. If it appears that the new information may result in an increase in dose for a completed dose reconstruction with a probability of causation of less than 50%, NIOSH is committed to working with the Department of Labor to reopen and rework the dose reconstruction, as appropriate. A Program Evaluation Plan (PEP) describes plans for evaluating specific program details or issues.

May 16, 2013
**About this Document:** New document to determine the effect on previously completed claims due to changes to Metallurgical Laboratory dose reconstructions.
**Summary:** With only one claim potentially affected by previous changes, the dose was recalculated for that claim using all currently approved methods. As a result of this recalculation, the probability of causation remained below 50%.Public Comments on Metallurgical Laboratory Documents
