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.

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 Harshaw Chemical Company.

Technical Documents

If the energy employee’s personal radiation information is incomplete, NIOSH will use other sources to estimate the radiation dose. This may involve using technical documents called Site Profiles, Technical Basis Documents, and Technical Information Bulletins.

Revised June 2, 2009

Revision Includes: Tables 5-6 and A-7 were modified and Figures A-3, A-4, A-5, A-8, A-9, and A-10 were replaced to correct an error in Rev 00. Figures A-1, A-2, A-6, and A-7 replaced to match the formatting of the modified figures. The footnote to Table B-25 was modified to clarify that the intakes listed are in terms of total alpha. The text in Section 5.9.5 was also modified to reflect this clarification. No comments were received as a result of formal internal review. Incorporates formal NIOSH review comments.

Program Evaluation Plans (PEPs) and Program Evaluation Reports (PERs)

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.

DCAS-PER-034 Rev-0: Harshaw Chemical Company TBD Revision [15 KB (2 pages)]
December 9, 2011

About this Document: Determines affect of revising the Harshaw TBD on previously completed claims.

Approved: December 9, 2011

Summary: Several editorial changes and clarifications were included in the revision however these changes do not affect the estimated dose. Some changes may have decreased the dose but the only significant increase in the dose estimate is caused by an increase in the estimated intake rate for type S uranium from 12/1/1949 to 12/31/1953. The values are listed in Table 5-6 of both revisions.
