Consequently, there were only very rough estimates, for which the total annual work duration was 140 man-hours and the average
dose rate was 0.03 mSv/h.
All the plans were prepared using the Oncentra Planning System version 4.1 (Elekta Inc., Stockholm, Sweden), which supports VMAT optimization; they were generated for 6-MV photons, with the maximum
dose rate maintained at 600 MU/min.
Therefore, equations (4), (5), and (6) are newly constructed to express REID as a function of
dose rate and duration of exposure in total body ionizing radiation in humans.
To apply different
dose rates during radiotherapy, multiple LINAC instruments can be used [22].
Transmission factor B [29] is defined as the ratio between the annual
dose rate at a given distance with shielding system (seeking for the annual dose to agree with the international restriction that depends on the definition of the type of adjoining zone, whether controlled or not controlled) and the annual
dose rate in the same point without shielding.
Energy fluency was converted into
dose rate using the dose energy (DE), dose function (DF), and tally multiplier (Fm) cards.
Equivalent
dose rate measurements were monitored at 10 cm from each side of the irradiator (front, rear, right and left), using a Thyac III Survey Meter.
(2012), who tested thiacloprid at
dose rate 0.45ml/L against four predatory mites, Neoseiulus cucumeris, Typhlodromips montdorensis, Iphiseius degenrans and Amblyseius swiriskii and found (18%, 4%, 56%, 10%) mortality after 24 h and (20%, 18%, 72%, 18%) mortality after 48 h respectively.
The geometry of hot leg pipe, linking the blanket and the heat exchanger, is adopted for
dose rate calculation here, which has an internal diameter of 0.527 m, thickness of 0.02 m, and length of 33 m.
While using dewormers care should be taken about
dose rate of dewormer because high dose of dewormer cause toxicity in the body of animals whereas under or low
dose rate have no effect on worms.
ERICA applies a screening
dose rate value of 10 [mu]Gy [h.sup.-1] for all types of organisms.
Observa gives live radiation
dose rate readings from multiple detectors simultaneously, making it the perfect system for use in larger sites, the company says.
