Deinococcus radiodurans, nicknamed 'Conan the Bacterium,' can survive acute gamma radiation doses of about 5,000 grays with no loss of viability and can tolerate up to 15,000 Gy with some survivors — thousands of times the dose lethal to humans (about 5 Gy). It survives via an extraordinarily efficient DNA double-strand break repair system.
The question, scope, and sources behind this Registry record.
Deinococcus radiodurans, nicknamed 'Conan the Bacterium,' can survive acute gamma radiation doses of about 5,000 grays with no loss of viability and can tolerate up to 15,000 Gy with some survivors — thousands of times the dose lethal to humans (about 5 Gy). It survives via an extraordinarily efficient DNA double-strand break repair system.
The highest acute dose of ionizing gamma radiation under which a population of the bacterium Deinococcus radiodurans shows no loss of viability, as established in laboratory irradiation studies.
Change a parameter to stress-test whether a proposed result is still inside the published specification. This is an audit aid, not a proof checker.
This record has no editable parameters. Read the formal question and assumptions before challenging it.
Current frontiers derived from accepted Claims.
An observed or demonstrated result; no opposing bound is implied.
The frontier is not sacred
Most progress starts with a disagreement that survives contact with evidence. If you can push the known lower bound up or pull the upper bound down, show us the work.
≥ when you have shown that at least this value is achievable.≤ when you have shown that anything above this value is impossible.No vibes. State the value, define the scope, and link the paper, proof, code, or reproduction that lets another person check it. Editors review every challenge before the public record changes.
