Avocado tolerates about 100-200 Gy (Thomas 2001), and the dose uniformity ratio (maximum absorbed dose divided by minimum absorbed dose) expected in commercial irradiation facilities can vary anywhere from 1.2-2.5, depending on the source and arrangement of irradiated product.
The 2 main concerns related to patient dose during CT scanning are skin dose (the absorbed dose to the most superficial layers of the skin) and dose distribution during the acquisition of the adjacent tomographic slices that make up a CT scan.
3) was measured and was added to "D" for accurate absorbed dose measurement.
I-124 behaves biochemically similar to I-131 and its physical half life of 4.2-days makes it suitable for sequential time point imaging and absorbed dose calculations.
Based on the definition of the dose and its transfer to a polymer molecule, we calculated the average number of radicals ([N.sub.r]) of PP H2150 for an absorbed dose (D) of 300 kGy and an overall G-value of PP ([G.sub.t] of 1.65 radicals per 100 eV absorbed energy.
Relative surviving fraction was determined as a function of the absorbed doses. Based on survival curves (Figure 1) an absorbed dose of 200 Gy was selected for combination treatments.
The response was studied for 4PNPAN/PVB films containing different dye concentrations in terms of the change in absorbance per unit thickness (IA.mm-1 ) at 472 nm against the absorbed dose (IA= Ao-Ai, where Ao and Ai are values of absorbance at 472 nm for un-irradiated and irradiated films respectively).
For example, for one complete rotation of the x-ray tube in a multislice CT scanner, all slices do not experience the same amount of absorbed dose due to radiation scatter inside the medium.
Although the high variability of bone marrow absorbed dose in relation to a given activity of I-131 can be influenced by many factors, the profound hematologic toxicity encountered in this patient lends credence to the theory that the cumulative effect of multiple doses can persist over time (5).
In addition to the equation 2, the introduction of the absolute value sign is to turn all negative values from measured absorbed dose into positive values.
It was noted that the rate of absorbed dose increased with the increase in the field size and decreased with the increase in depths.
Chester Reft from University of Chicago USA made a presentation on Dosimetry in radiation therapy by using different types of detectors and dosimeters used in small field Dosimetry and absorbed dose. His other presentation was on In-vivo Dosimetry for patients undergoing external beam radiotherapy.
