. Measured 222Rn ranged from 0.26±0.01 to 0.88±0.09 Bq l-1 and 0.25±0.02 to 0.72±0.10 Bq l-1 in the drilled wells and dug wells respectively. The activity concentrations were used with ingested dose conversion factors to estimate annual effective dose rates due to ingestion of 222Rn ...
In the present work, we have measured the specific activity and the radiation hazard indices in fifteensamples, which include five for solid sample an..Nada F. KhadhimOmer H. Adnan

(CHS). A T cell-mediated and antigen-specific inflammatory response in which the exposure of epidermal cells to exogenous haptens results in a delayed-type hypersensitivity reaction that can be experimentally measured and quantified. Chromophores The parts of a photoreceptor that absorb photons of lig...
An extrapolation of double event rates with activity is expected to scale linearly, thus allowing for predictions for specific scenarios. For example, most radiation accidents caused by lost or stolen sources in the late 20th century involved sources with activities >100 GBq28, thus being more ...
[76]. A significant (3-fold) increase in the activity of NADH oxidase was measured in purified plasma membranes from HeLa cells exposed to 875 MHz for 5 or 10 min at a power density of 200 μW/cm2. This exposure intensity is significantly lower than the ICNIRP [5] safety limit...
Thoron concentration levels were measured in the high background radiation area located in Zhuhai city using solid-state nuclear track detectors.Measurements were carried out quarterly at each location throughout a year.Totally 96dwellings were selected for the study.Thoron concentration is vary between...
For an administered activity of 370 MBq of18FDG, the effective dose from PET/CT investigations was estimated to be 14.2 mSv in males and 17.2 mSv in females. The present results did not demonstrate significant difference in the kinetics of18FDG distribution in male and female patients. The ...
2a,b). Therefore, Sfp53 protein seems to ‘accumulate’ in response to radiation. This indicated that Sfp53 may have similar functional activity following radiation stress as is classically established for human p53. However, the radiation-induced accumulation of Sfp53 at sublethal doses was not ...
Preoperative radiation is associated with an increased risk of wound complications. However, the influences of radiation on musculofascial wound healing remains unclear. The purpose of the study was to investigate the short-term effects of preoperative local radiation on the musculofascial healing of la...
