category‚ the number (N) and percentage (%) of screened children whose highest blood lead specimen fell within the category is shown. Blood lead levels in the 10-24 µg/dL category are considered elevated and blood lead levels ≥25 µg/dL signify lead poisoning. Also‚ the CDC uses a new reference level of 5 µg/dL to identify children whose blood lead levels are higher than 97.5% of all U.S. children’s levels‚ based on the National Health and Nutrition Examination Survey (NHANES). However‚ there is no safe

Food poisoning is caused by eating organisms or toxins present in food or drinks. Staphylococcus or E. coli is one of the commonest bacteria which results in food poisoning. Due to improper handling‚ this kind of a contamination happens. Even though it is a very common condition it can get worse depending on the degree of contamination. Some common foods which can cause food poisoning if proper care is not taken are raw poultry‚ unpasteurized milk‚ red meat‚ poisonous mushrooms‚ pesticides on fruits

One day‚ one of his daughters came down with typhoid fever‚ a form of food poisoning. Within a few days half of the people in the home had become sick. Nobody could figure out where the typhoid had came from‚ so a man named George Soper‚ who was a sanitary engineer‚ decided to investigate. He tested the waters and found nothing wrong

USES OF RADIATION BY: Sanwal Hayat What is radiation? Radiation is away in which energy moves from one place to another for example energy radiates away when a stone dropped in the water in circular waves while sound energy radiates from speakers mouth to listeners ear and heat energy radiates from sun to earth.

Indeed‚ radiation deteriorates vision. As well‚ it can damage it. For example‚ some people like to sit close to TV sets. Their eyes are too close to the screen and radioactive rays are constantly getting in their eyes. For that reason‚ television harms people’s vision. Television sends out radiation that has

Cell Phone Radiation Written by: Jacob Nickerson Cell phone radiation is something we as consumers are exposed to each and every day. What effect does this have on us? Can this radiation alter the cell structures and functions of our bodies? For what amount of time can our bodies be exposed to this radiation without health risks? These are all questions many scientists and researchers are trying to answer with every day that passes. Researchers are divided on a conclusion of whether or not

word ’radiation’ has to do with energy or matter moving through space. Space radiation affects astronauts when an amount of radiation gets through the walls of a space shuttle or station and enters the body. Solar radiation usually affects astronauts walking in space‚ outside of their space shuttles‚ but sometimes it can even affect the people on Earth‚ causing electricity failures. Many people - astronauts mostly- fear the consequences of solar radiation‚ due to the fact that solar radiation can cause

The History of the Discovery of Radiation and Radioactivity Introduction: Radiation can be defined as the propagation of energy through matter or space. It can be in the form of electromagnetic waves or energetic particles. Ionizing radiation has the ability to knock an electron from an atom‚ i.e. to ionize. Examples of ionizing radiation include: • alpha particles • beta particles • neutrons • gamma rays • x-rays Non-ionizing radiation does not have enough energy to ionize atoms in the material

Research on Conduction‚ Convention‚ and Radiation Conduction is the exchange of warmth between substances that are in direct contact with one another. The better the conductor‚ the all the more quickly warmth will be exchanged. Metal is a decent conduction of warmth. Conduction happens when a substance is warmed‚ particles will acquire vitality‚ and vibrate more. These atoms then chance upon adjacent particles and exchange some of their vitality to them. This then proceeds with and passes the vitality
