Sentence examples for fractionated exposure from inspiring English sources

As Preston et al (2002) found no evidence that fractionated exposure resulted in a lower risk of radiation-induced breast cancer than acute exposure, a dose rate reduction effectiveness factor was not included in these calculations.

Another important difference in our experimental model is that we delivered radiation exposure in a single, unfractionated dose to late third-instar larvae, whereas CRT generally utilizes fractionated exposure delivered in smaller doses over many days to achieve a final total dose to reduce toxicity to normal tissue while effectively killing malignant cells (Ahmed et al., 2014).

In Trp53 normal mice, this very low chronic fractionated exposure accelerated the appearance of spontaneous lymphomas after exposure times up to 60 weeks, reducing average lifespan and indicating that a lower dose threshold for protective effects from this level of radiation stress had not been reached.

However, with the smallest fraction (1%), the effect was not different from a single-train exposure, irrespective of the fact that the fractionated exposure lasted 6 min and the single train was delivered in 0.6 s.

Ilnytskyy et al have shown that PBIR induced different epigenetic responses in bystander organs such as skin and spleen (Ilnytskyy et al, 2009), although a similar response was induced in the same organism by acute or fractionated exposure.

Previous studies have shown that partial body irradiation induced different epigenetic responses in bystander organs such as skin and spleen (Ilnytskyy et al, 2009), whereas no differential response was seen in the same organism by acute vs fractionated exposure.

The individuals from this accident were exposed to protracted, fractionated exposures.

However, the individuals from this accident were exposed to protracted, fractionated exposures, and the possibility exists that long-term stability may not be observed under these irradiation conditions.

This research has shown a significant decline in stable rearrangements after 16 months and affords the opportunity to test the long-term stability of these aberrations after protracted, fractionated exposures.

For example, patients undergoing radiotherapy, who generally receive fractionated exposures of 1 5 Gy per fraction and cumulative doses of 15 >50 Gy, have lower risks per unit dose than atomic bomb survivors, who received a single acute exposure primarily <2 Gy [19].

The strong radioresistance of normal brain vasculature [9], [10] to spatially fractionated exposures to MBs may prevent the decrease in brain perfusion and hypoxia observed after conventional radiotherapy [11], [12].
