  • Advanced Enviro-Septic™ Systems Achieve Even Distribution without Pressure Dosing

    Abstract: Advanced Enviro-Septic™ Systems (AES) do not use pressure distribution. Pumps are used only if necessary to gain elevation to the treatment field. Pressure distribution has the potential to disrupt the settling of solids within the pipe. Testing has confirmed that AES achieves even distribution throughout the system naturally, through the development of a controlled bacterial ...

  • Suicides and exposure to low doses of ionising radiation

    The suicide rates in southern India are very high (Joseph et al., 2003; Aaron et al., 2004), where there are areas of high natural radiation background (UNSCEAR, 2000). It was a stable tendency towards excess of suicides among the atomic bomb survivors exposed to low doses (0?90 mGy) (Kusumi et al., 1993). It was informed about the direct dependence between the suicide rate and the residency ...

  • Excessive sulfuric acid dosing resulting in irreversible scale formation

    Many consultants in the RO water treatment industry recommend sulfuric acid dosing into the feed water as a safety measure. This case study reviews a situation where acid dosing was used with the intention of improving system performance but resulted in severe sulfate scaling. The difficulties in cleaning sulfate scales are discussed and after numerous lengthy trials, an effective cleaning ...

  • An analysis of the correlation between the non-cancer morbidity of children and the internal dose of 137Cs

    This paper sets out to accomplish the following: (i) to define the relationship of child morbidity of the digestive system with the low radiation internal dose, taking into account the environmental landscape-geochemical conditions of residence territory and the age peculiarities of children, (ii) to select groups composed of children 0-14 years old and who live in analogical environmental and ...

  • Four years experience with a new chlorine dosing regime against macrofouling

    A new method of chlorination called Pulse-Chlorination® was developed by KEMA in 1998. Pulse- Chlorination is based on the principle that mussels and clams, in general have a recovery period before full opening and start filtering after exposure to a chlorination period. The chlorination method takes advantage of this recovery time by using short successive periods of chlorination, alternating ...

  • Damage propagation in complex biological systems following exposure to low doses of ionising radiation

    Biological organisms present hierarchical levels of organisation capable of maintaining homeostasis at low-level perturbations through intricate signalling between cells. Ionising radiation may damage DNA and other molecular components. This primary risk rises linearly with dose over a certain dose range. A second risk describes the probability of the initial DNA and other damage to propagate in ...

  • Predicted and observed therapeutic dose exceedances of ionizable pharmaceuticals in fish plasma from urban coastal systems

    Instream flows of the rapidly urbanizing watersheds and estuaries of the Gulf of Mexico in Texas (USA) are increasingly dominated by reclaimed waters. Though ionizable pharmaceuticals have received increasing attention in freshwaters, many research questions remain unanswered, particularly in tidally influenced urban coastal systems, which experience significant spatiotemporal variability in ...

  • Low-dose monitoring for occupational exposure and the influence of measurement accuracy

    This paper presents the evolution of individual radiation doses received by occupationally exposed workers. The individual doses accumulated over the period 2000-2007 correlated to nuclear laboratory and radiation source (gamma, X-rays) types are in the low radiation range. Dose equivalent Hp(10) was measured by a film dosimeter system; the influence of the measurement accuracy on the results was ...

  • Effect of iodine chemical form on thyroid doses during a severe accident

    In most of the accidents that may occur in nuclear reactors, the short-term radiological consequences are expected to be dominated by isotopes of iodine. The assessment of doses resulting from iodine release during a severe reactor accident requires knowledge of the iodine chemical forms and removal mechanisms prior to the release to the environment. In this paper, the arguments concerning iodine ...
