Scientists do not know whether low levels of radiation exposure carry health risks
Indicate whether the statement is true or false
TRUE
Explanation: Much of our knowledge base regarding the negative effects of exposure to radiation comes from extrapolated data using high doses and dose rates. Scientists do not know whether a threshold level exists, below which radiation would be safe. To err on the side of caution, the radiation protection community assumes that any dose of radiation may pose a risk.
