DLP is a more realistic indicator of the radiation dose and, in calculating the DLP, the measure of CTDIvol is still required.
CTDIvol given in milligrays (mGy) is an accurate indicator of the radiation dose per slice within the scanned volume [1, 36, 37, 38, 39].
Thus, DLP is an indicator of the integrated dose of an entire CT examination.
Therefore, UCd is considered to be a useful indicator of the internal dose of Cd exposure.
The blood concentration is generally considered the appropriate indicator of the absorbed dose and the amount systemically available.
We found that attack rates were not a reliable indicator of the infectious dose received since the majority of exposed animals became affected.
Whereas pollen concentration has been taken as the indicator of potential dose, the underlying mechanism for allergic symptoms comes in part from the protein allergens in the pollen (Ahlholm et al., 1998; Beggs, 1998; Singer et al., 2005).
DLP correlates better with the patient radiation dose than CTDIvol and can easily be used as an indicator of the given radiation dose.
Standard statistical analyses assume that exposure biomarkers are measured without error, which is not possible because they are merely proxy indicators of the true dose to the brain.
The design of this study was originally intended to enable comparison between experimental exposure groups and the positive control Groups 5 to 7, which experienced exposure typical of that in VLA scrapie flock, using survival times and attack rates as indicators of the infectious dose received.
Biomonitoring for insecticide metabolite concentrations in urine is a commonly used indicator of internal dose integrating the various routes through which the contaminant enters the body (Barr et al. 1999).
