2.0 LITERATURE REVIEW 2.1 History background and action level Radon is a gaseous highly radioactive element discovered by English physicist Ernest Rutherford in 1899. The discovery is also credited to German physicist Friedrich Ernst Dorn in 1900. More specifically, Rutherford discovered radon's alpha radiation and Dorn discovered that radium was releasing a gas. Radon (chemical symbol Rn) is a naturally occurring radioactive gas found in soils, rock, and water throughout the U.S. It has numerous different isotopes, but radon-220, and radon-222 are the most common (EPA, 2009).
Bodybuilders Drink Milk/Eggs: Milk contains two types of high-quality protein. For bodybuilders, it is especially important to consume a diet with adequate amounts of protein to allow for the rebuilding and repair of muscle tissues. Milk is unique in that it contains two types of high-quality protein, which each possess different characteristics. The combined proteins in milk make it an ideal drink for bodybuilders, particularly when used after workouts.
Goat 's milk is additionally very vitamins and mineral thick. It has practically 35 % of your day-to-day needs for calcium in one cup. Exceptionally high in riboflavin, simply one mug of goat 's milk supplies 20.0 % of our day-to-day demands. Include in that high amounts of phosphorous, Vitamin Protein, b12 and potassium. In fact, Ghandi himself renewed his own health and wellness after very long periods of fasting through drinking raw goat 's milk [
The same thing applies to Vitamin D pills, till now no one knows what amount is safe and an overdose would lead to HyperCalcemia , which produces Kidney stones, meddles with your heart and brain, and damages your bones. Still, Vitamin D experts are increasing the daily amount needed well aware of the risks. So, some people opt for what they consider the safest way to get Vitamin D – Food. Vitamin D is commonly found in Dairy products , fatty fish, orange juice , egg yolks…etc. Nevertheless, one requires
Cow’s milk is often described as nature’s most wholesome food. Cow’s milk contains most of the same composition as human milk; however, these compositions are not in the same amounts. For example, humans have the most advanced brains of all species on earth, therefore human milk has evolved into having high levels of PUFAs or polyunsaturated fatty acids (especially linoleic acid) which is responsible for the rapid brain development (onegreenplanet website). Cow’s milk, on the other hand, contains significantly lower amounts of PUFAs, but higher levels of saturated fats, which contribute to rapid body building.
It is also one of the farthest planets from our solar system, which causes it to take 4 hours for the sunlight to reach Neptune. Surprisingly, the sunlight we have here on Earth is 900 times brighter on Neptune! Since, Neptune is the windiest planet in our solar system it contains supersonic winds, winds that are 1.5 times faster than the speed of sound. The planet is at least -300 fahrenheit and the hottest it can get is 18 degrees fahrenheit. Neptune has a radius of 15,299.4 miles, it is also four times
In Magnesium there are 12 electrons, 12 neutrons, and 12 protons. It’s not usually common for the electrons , neutrons, and protons are the same. Magnesium is a solid. It’s melting point is 650C and the boiling point is 1107C. Its in group number 2 period number 3 the group name is Alkaline Earth Metal. Magnesium is
Anthracite Anthracite is the highest rank of coal. It has a carbon content of over 87% on a dry ash free basis. Anthracite coal usually has the highest heating value per ton on a mineral matter free basis. It is often subdivided into semi anthracite, anthracite, and meta-anthracite on the basis of carbon content in the coal. Anthracite is frequently referred to as "hard coal"; however, this is a layman's term and has little to do with the hardness of the
This metal was first discovered by a man called Humphry Davy, in 1808 through the process of electrolysis while doing a mixture of lime (CaO) and mercuric oxide (HgO). Calcium is one of the most abundant elements on earth, forming over 3% of the earth's crust. It has 6 stable and several radioactive isotopes Calcium is the third most abundant metal in the earth’s crust, but
Today, however, the penny consists of ninety-seven and a half percent zinc with only a thin copper skin. Copper holds the third spot in most consumed industrial metals, according to U.S Geological Survey. In fact, electrical wires, telecommunication cables and electronics make up three-quarters of copper. Besides gold, copper is the the only other element that is not naturally silver/grey. Today, about two thirds of copper comes from is found in volcanic rocks.
