Shifting the paradigm in radiation safety.
The current radiation safety paradigm using the linear no-threshold (LNT) model is based on the premise that even the smallest amount of radiation may cause mutations increasing the risk of cancer. Autopsy studies have shown that the presence of cancer cells is not a decisive factor in the occurrence of clinical cancer. On the other hand, suppression of immune system more than doubles the cance...
متن کاملRadiation safety: New international standards
by Abel J. Gonzalez B*y the end of the 1980s, a vast amount of new information had accumulated to prompt a new look at the standards governing protection against exposures to ionizing radiation and the safety of radiation sources. First and foremost, a re-evaluation of the radioepidemiological findings from Hiroshima and Nagasaki suggested that exposure to lowlevel radiation was riskier than pr...
متن کاملSafety I to Safety II: A Paradigm Shift or More Work as Imagined?; Comment on “False Dawns and New Horizons in Patient Safety Research and Practice”
In their editorial, Mannion and Braithwaite contend that the approach to solving the problem of unsafe care, Safety I, is flawed and requires a shift in thinking to what they are calling Safety II. We have reservations as to whether by itself the shift from Safety I to Safety II is sufficient. Perhaps our failure to improve outcomes in the field of patient safety and quality lies less in our ap...
متن کاملTowards a New Paradigm of UAV Safety
With the rising popularity of UAVs in the civilian world, we are currently witnessing and paradim shift in terms of operational safety of flying vehicles. Safe and ubiquitous human-system interaction shall remain the core requirement but those prescribed in general aviation are not adapted for UAVs. Yet we believe it is possible to leverage the specific aspects of unmanned aviation to meet acce...
