For such purposes, doses should be evaluated in terms of absorbed dose (in gray, Gy), and where high-LET radiations (e.g., neutrons or alpha particles) are involved, an absorbed dose, weighted with an appropriate RBE, should be used" Radiation weighting factors are largely based on the RBE of radiation for stochastic health risks. However, for ...
The RBE is generally independent of LET for any LET less than 10 keV/μm, so a low LET is normally chosen as the reference condition where RBE is set to unity. Above 10 keV/μm, some systems show a decline in RBE with increasing LET, while others show an initial increase to a peak before declining.
The detailed RBE vs. LET relationship that was found for total exchanges is similar to that of earlier studies of mutation [11] [12] and in vitro neoplastic transformation. [13] For all of these endpoints, RBE peaks at around 100 to 200 keV/μm before it decreases at very high-LET. However, the quality of chromosome damage is different when ...
If your kids do not want to get up and go to that thing with you this week, let them.” “So much time and energy is wasted on forcing other people to match our expectations,” Robbins continued.
Another overdosed on the couch, and his parents thought maybe they should just let him go. Northern Kentucky Hit Hard By Heroin Overdoses Between 2011 and 2014, heroin overdoses at five Kentucky emergency rooms outside of Cincinnati — Covington, Ft. Thomas, Edgewood, Florence and Grant County — increased by 669 percent.
Rather than plotting your actions, let the universe show you what direction you're headed in. The moment has finally come for you to embrace your fiery and impulsive sentiments by carpe-diem-ing ...
Radiation with higher LET and higher relative biological effectiveness (RBE) have a lower OER in mammalian cell tissues. [2] The value of the maximum OER varies from about 1–4. The maximum OER ranges from about 2–4 for low-LET radiations such as X-rays, beta particles and gamma rays, whereas the OER is unity for high-LET radiations such as ...
