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.

Timeline of Major DCAS Events for 2006

Establishing the foundation for conducting dose reconstructions as required under the Energy Employees Occupational Illness Compensation Program Act (EEOICPA) has been an important and busy time for our Office. Major events of our dose reconstruction program are listed below.
