Because the exposure duration was short (4 hr), relatively high exposure doses (50 and 100 mg/[m.sup.3]) were selected so that the DEP effects can be clearly analyzed.
In order to approximate the amount of EcoSan sludge ingested by people, men aged between 20 and 50 years owning and using EcoSan toilet were used to estimate exposures doses as it was difficult to approximate exposure doses for every member of the household.
Based on available literature we selected five different radiant exposure doses to irradiate blood (2.4 J/[cm.sup.2], 4.9 J/[cm.sup.2], 9.9 J/[cm.sup.2], 19.8 J/[cm.sup.2], and 39.5 J/[cm.sup.2]).
However, the daily exposure dose recorded through the general food intake (DEDFI) must be added to that DED recorded for children through plants infusion considering the fact that children are exposed to the same metal via other foods in the same way as the general population [24].
A higher value of the exposure dose indicates a higher impact on occupants.
Thus, all 3 hosts (GSW farmed abalone, wild-caught juveniles and wild-caught adults) demonstrated similar mortality curves, resulting in similar cumulative mortalities for the 3 exposure doses used.
Calculating parameters Values Note Concentration of ([mu], [sigma]) Follow Gaussian the pollutants C (mg/L) distributions Reference dose mg/(kg * d) RfD By mouth Exposure volume at one 100 time V (mL) Exposure times per year (n) 40 Average body weight (kg) 70 Average lifespan (a) 70 Average exposure dose per d = (n x V x unit of body mass [10.sup.-3] x C)/365 x 70 Lifelong health risk P P = d x [10.sup.-6]/RfD Individual health risk Pa Pa = P/70 Maximum acceptable 1.0 x [10.sup.-6] risks [9] TABLE 3: The quantile table of the life risk and the annual risk of DiOP.
The cold shutdown is also defined by the government and TEPCO as a state in which the release of radioactive materials from reactors is under control and radiation exposure dose is significantly held down.
Researchers fear children may be more vulnerable to mobile radiation because the exposure dose received by a child's brain is higher than that of an adult.
The potential dermal exposure dose was then extrapolated from the 8 h TWA paraquat deposition on each three passive samplers in 'ng paraquat per cm2' to 'mg paraquat per kg per day'.
Hence, a beam's power (watts), exposure duration (seconds), and irradiance diameter or spot size (in [cm.sup.2]) must be known to determine the exposure dose or radiant exposure (Joules/[cm.sup.2]).
It serves as a shielding material in the collimator, which absorbs stray radiation and limits the X-ray exposure dose.
