Determinations regarding contraction of covered illnesses
(a) Cases determined under part B
A determination under part B that a Department of Energy contractor employee is entitled to compensation under that part for an occupational illness shall be treated for purposes of this part as a determination that the employee contracted that illness through exposure at a Department of Energy facility.
