Just in time to debunk the US NRC proposal for increasing radiation exposure to the general population from 0.25 mSv (EPA) to 100 mSv: http://www.regulations.gov/#!docketDetail;D=NRC-2015-0057 (Comment Deadline Nov. 19th) is a new study of nuclear workers exposed to cumulative doses with a median average (half-above, half-below) of 4.1 mSv, and an overall arithmetic average (mean) of 20.9 mSv: “Results suggest a linear increase in the rate of cancer with increasing radiation exposure. The average cumulative colon dose estimated among exposed workers was 20.9 mGy (median 4.1 mGy). The estimated rate of mortality from all cancers excluding leukaemia increased with cumulative dose by 48% per Gy (90% confidence interval 20% to 79%), lagged by 10 years“. (See Richardson et. al. below). One Gy is 1000 mSv, in the context of this study, or 10 years worth of the US NRC 100…

Probe after Gorgon releases millions of tonnes of greenhouse gas

Emma Young10 May 2018 — 1:29pm

The Gorgon Gas project off WA’s north-west coast has released millions of tonnes of carbon dioxide into the atmosphere instead of injecting it underground as environmental approvals required, because of technical problems with its gas injection system.

The conditions stated that Chevron had to “implement all practicable means” to reinject all carbon dioxide removed during gas processing into deep aquifers below the island.

The Chevron-operated Gorgon Project. off WA’s coast.

The minimum requirement was 80 percent, calculated on a five-year rolling average. If the amount fell significantly below 80 per cent Chevron had to report this and take steps to “offset” these emissions.

The Barrow Island operation had still not yet injected any carbon dioxide underground, West Australian Environment Minister Stephen Dawson confirmed in Parliament on Tuesday in response to a question from…
