  • Ionising Radiation

    Introduction The energy level of some types of radiation is high enough so that when they interact with matter they cause the formation of electrically charged particles or ion-pairs and break molecular bonds. These so-called ionising radiations are by their nature potentially harmful to life; at high doses they can be lethal and at lower doses can cause genetic damage. Ionising radiation occurs ...

  • Radiation prevents much cancer

    Evidence reviewed here supports the concept that chronic exposure to ionising radiation can dramatically decrease cancer incidence and mortality. This evidence includes an inverse relationship between radiation levels and cancer induction and/or mortality in: over 200 million people in the USA; 200 million people in India; 10,000 residents of Taipei who live in cobalt-60 contaminated homes; high ...

  • How To Recycle Scrap AC Radiator

    Every scrapper’s dream is to find a “jackpot” of metal that is ripe for the picking. If you have any type of experience under your belt, you’ll know that “jackpots” are not happened upon often...unless, you happen to find an AC radiator. These are the non-ferrous tube systems that are used to compress air and radiator off heat. The bigger the AC unit, ...

  • Safe Recycling of Municipal Sludge by Gamma Radiation

    Abstract Municipal sludge contains many toxic organic materials, large number of pathogenic microorganisms, heavy metals alongside many nutrients beneficial to plant and/or animal growth, but its use is limited due to these health hazards contaminants. The technology of irradiation-pasteurization has been shown to quickly, efficiently and reliably deal with potential health hazards ...


  • Re-examining the health effects of radiation and its protection

    The health effects of radiation from atomic explosions in Japan were completely different from those due to radiation from the Co-60 contaminated apartments in Taiwan. The sudden exposure to acute radiation in extremely high doses killed Japanese people, and harmed the survivors in lower doses as shown by increased cancer mortality, especially the leukemia based on the LNT model. The chronic ...

  • Water disinfection by solar radiation in a green house effect device

    The water-borne diseases are major concerns in developing countries since they are the main cause of sickness and death among the population in rural communities. The traditional methods such as chlorination and the use of fuelwood to boil water has important environmental consequences and in some cases are rejected by population. The solar water heaters are considered as an effective, low cost ...

  • Why is there no effective real-time Continuous Radiation Monitoring System?

    Japan's disaster has raised many questions regarding safety of the public. It has served as a wakeup call to the agencies tasked with protecting the public. Not least of these questions, but certainly the most far-reaching is the question of the safety of nuclear power and radiation contamination of air and water. Way back when nuclear power was first established, in the 1960s public opinion was ...

  • Advanced process of microbiological control of wastewater in combined system of disinfection with UV radiation

    The purpose of this study was to present a methodology with superior efficiency for inactivating pathogenic indicators commonly found in domestic sewage. The adopted method was based on synergistic effect resulting from the introduction of a UV radiation pre-disinfection stage of sewage followed by secondary treatment. A pilot unit was installed in the sewage treatment plant of the University of ...

  • Geostatistical Methodology For Waste Optimization Of Contaminated Premises

    Summary At the end of process equipment dismantling, the complete decontamination of nuclear facilities requires the radiological assessment of residual activity levels of building structures. As stated by the IAEA: “Segregation and characterization of contaminated materials are the key elements of waste minimization”. From this point of view, the set up of an ...

  • Modeling of coastal water contamination in Fortaleza (Northeastern Brazil)

    An important tool in environmental management projects and studies due to the complexity of environmental systems, environmental modeling makes it possible to integrate many variables and processes, thereby providing a dynamic view of systems. In this study the bacteriological quality of the coastal waters of Fortaleza (a state capital in Northeastern Brazil) was modeled considering multiple ...

  • Cadmium regarded as the most serious contaminant of the modern age

    Abstract Cadmium is today regarded as the most serious contaminant of the modern age. It is absorbed by many plants and seacreatures and, because of its toxicity, presents a major problem for foodstuffs. Contamination through fertilisers becomes an increasing problem. Unlike lead, cadmium contamination cannot be removed from plants by washing them; it is distributed throughout the organism. It ...

  • NORMs contamination treatment using Ivey-sol technology

    NORMs (naturally occurring radioactive materials) are found almost everywhere, and many natural materials, such as the earth’s crust, contain such radioactive materials. So what happens when oil and gas activities such as petroleum refining and natural gas extraction, disturb such radioactive material? They can alter the natural background radiation — the radiation that we are naturally exposed ...

  • Food contamination after the Chernobyl accident: dose assessments and health effects

    After the Chernobyl accident, a tendency to overestimate its medical consequences was noticed in many scientific publications, a recent example being the volume 1181 of the Annals of the New York Academy of Sciences, entirely dedicated to Chernobyl. In the present paper, several statements from the chapter 'Radioactive Contamination of Food and People' are discussed and their reliability ...

  • GOOD NEWS FOR DRINKING WATER Independent Test Lab Evaluates Instrumentation forDetecting Radiation in Drinking Water

    Since 9/11 and there are still holes in security of the nation’s infrastructure, particularly for drinking water. This security deficit is currently being addressed in some community water systems with water monitoring instruments. In the 90s the EPA developed a wish list for monitoring contaminants in drinking water. Since that time biological and chemical contaminants have been identified ...
