Radioactive contamination, also called radiological pollution, is the deposition of, or presence of radioactive substances on surfaces or within solids, liquids, or gases (including the human body), where their presence is unintended or undesirable (from the International Atomic Energy Agency (IAEA) definition).
Jiří Hála claims in his textbook "Radioactivity, Ionizing Radiation and Nuclear Energy" [6] that cattle only pass a minority of the strontium, caesium, plutonium and americium they ingest to the humans who consume milk and meat. Using milk as an example, if the cow has a daily intake of 1000 Bq of the preceding isotopes then the milk will ...
There are five types of air pollution dispersion models, as well as some hybrids of the five types: [1] Box model – The box model is the simplest of the model types. [2] It assumes the airshed (i.e., a given volume of atmospheric air in a geographical region) is in the shape of a box.
Beta attenuation monitoring (BAM) is an air monitoring technique employing the absorption of beta radiation by solid particles extracted from air flow. The technique allows for the detection of PM 10 and PM 2.5, which are monitored by most air pollution regulatory agencies.
Radiation is often categorized as either ionizing or non-ionizing depending on the energy of the radiated particles. Ionizing radiation carries more than 10 electron volts (eV), which is enough to ionize atoms and molecules and break chemical bonds. This is an important distinction due to the large difference in harmfulness to living organisms.
Air pollution can occur naturally or be caused by human activities. [3] Air pollution causes around 7 or 8 million deaths each year. [4] [5] It is a significant risk factor for a number of pollution-related diseases, including heart disease, stroke, chronic obstructive pulmonary disease (COPD), asthma and lung cancer.
Increased levels of stress, air & light & noise pollution, and reduced "green" space are all urban-associated environmental effects that are adversely linked to mental health. [3] Though urban areas are often correlated with dirtiness and disease, they are likely to have more access to higher quality health care which can lead to more positive ...
PUFF-PLUME is a model used to help predict how air pollution disperses in the atmosphere. It is a Gaussian atmospheric transport chemical/radionuclide dispersion model that includes wet and dry deposition, real-time input of meteorological observations and forecasts, dose estimates from inhalation and gamma shine (i.e., radiation), and puff or continuous plume dispersion modes.
