In the mid-1990s, the technetium-99 discharges from Sellafield to the Irish Sea increased, growing from a few TBq per year to a peak of 190 TBq in 1995. The technetium-99 discharges remained relatively high until 2003-2004, when Sellafield implemented new technology to remove technetium-99.
During the last few years, the discharges have been below 10 TBq per year, and the discharge in 2016 was 1.9 TBq.
