            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.

The SEC was established by the Act/EEOICPA. 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:
have at least one of the 22 SEC cancers and
have worked for a specific period of time at one of the SEC work sites.The Act also allows for additional groups of employees (called classes of employees) to be added to the SEC. Classes of employees and work sites can be considered for addition to the SEC through a petition process run by NIOSH.
To help individuals interested in the petition process, NIOSH has an SEC Petition Counselor and an Ombudsman to NIOSH.

SEC Rule
The SEC Rule, Procedures for Designating Classes of Employees as Members of the SEC (42 Code of Federal Regulations, Part 83),  PDF [132 KB (13 pages)] describes the procedures used to add a class of employees to the SEC.

Petitions are submitted by authorized parties
Petitions are justified
Petitions are given uniform, fair, and scientific consideration
Petitioners are given the opportunity to be involved with the petition processTopics Covered under the SEC Rule:
How HHS will determine:
if it is feasible to estimate the radiation dose that a class received, and
if there is a reasonable likelihood that the radiation dose may have endangered the health of members of the class
The procedures that are necessary to add a class of employees to the SEC
Individuals and organizations that are qualified to submit an SEC petition on behalf of a class
Minimum requirements that must be met for an SEC petition to qualify for consideration
Procedures to involve and notify petitioners in the petition process and to allow petitioners to seek administrative reviews of proposed decisions
SEC Cancers
In addition to having worked for a specific period of time at one of the SEC work sites, a covered employee must also have at least one of the following types of cancer to qualify for compensation under the SEC:
Bone cancer
Renal cancers
Leukemia (other than chronic lymphocytic leukemia) provided the onset of the disease was at least two years after first exposure
Lung cancer (other than in-situ lung cancer that is discovered during or after a post-mortem exam)

Classes Added to the Special Exposure Cohort (SEC)
A “class of employees” is defined in the SEC rule as a group of employees who work or worked at the same DOE facility or AWE facility, and for whom the availability of information and recorded data on radiation exposures is comparable with respect to the informational needs required to complete a radiation dose reconstruction as required under The Act.
