Examples of Reference dose in a sentence
Reference dose (RfD): Description and use in health risk assessments.
Reference dose" is a value representative of a daily exposure level for the human population, including sensitive subpopulations, that is not likely to cause an adverse non-cancer health effect during a specified period of time (for example, an acute, short-term, subchronic or chronic exposure period).
The piezocone has a standard (ASTM D-3441) 10 cm2 60° conical tip and a 150 cm2 friction sleeve.
The HQ is calculated as follows: Non-cancer HQ = CDI/RFD where: CDI = Chronic Daily Intake RfD = Reference dose; and CDI and RfD are expressed in the same units and represent the same exposure period (i.e., chronic, sub-chronic, or short-term) The results of the risk calculations indicated that the hazard index (HI) for the current worker scenario is below 1.0, the level of concern for noncarcinogens.
Reference dose media evaluation guide (RMEG) values are estimated daily oral or inhalation contaminant concentrations at which noncarcinogenic health effects are unlikely to develop over a lifetime of exposure.
