INL makes a case for eliminating ALARA and setting higher dose limits
A report just released by Idaho National Laboratory reviews decades of radiation protection standards and research on the health effects of low-dose radiation and recommends that the current U.S. annual occupational dose limit of 5,000 mrem be maintained without applying ALARA—the “as low as reasonably achievable” regulatory concept first introduced in 1971—below that threshold.
Noting that epidemiological studies “have consistently failed to demonstrate statistically significant health effects at doses below 10,000 mrem delivered at low dose rates,” the report also recommends “future consideration of increasing this limit to 10,000 mrem/year with appropriate cumulative-dose constraints.”

In this study, tritium transfer from foods Organic Bound Tritium or tritiated water to DNA was measured by E. coli cell and tritium concentration in DNA during fusion plant operation was estimated. Measured tritium concentration in DNA was much lower than estimated value based on the atomic ratio of culture medium. In addition, contribution of organic bound tritium in our food to calculated tritium concentration in DNA was greater than the contribution to tritium dose.
