Answer: Marie Curie died on 4 July 1934, in Savoy, France. She died of aplastic anaemia, a blood disease that often results from exposure to large amounts of radiation. … She later changed her name to ‘Marie’ when she moved to Paris, France in later years. Did Marie Curie’s kidsRead More →
Getting Too Close to ‘Radioactive’ … Even medical and scientific words, which tend to have very specific meanings, such as radioactive. The figurative use of the word now typically carries the meaning of “so divisive or controversial as to require avoidance.” What happens when a human is radioactive? Exposure toRead More →
Since the rate of radioactive decay is first order we can say: r = k1, where r is a measurement of the rate of decay, k is the first order rate constant for the isotope, and N is the amount of radioisotope at the moment when the rate is measured.Read More →
Why some elements are radioactive (unstable). When the atoms of an element have extra neutrons or protons it creates extra energy in the nucleus and causes the atom to become unbalanced or unstable. Whether radioactive elements can become stable and if so, how. The unstable nucleus of radioactive atoms emitRead More →
The Department of Defence website explains the importance of the Woomera Prohibited Area which lies beyond the village and is not open to visitors. It explains that “The Woomera Prohibited Area (WPA) is a globally unique military testing range. What happened Woomera? Woomera Village initially operated as a “closed town”Read More →
Radiation cannot be spread from person to person. Small quantities of radioactive materials occur naturally in the air, drinking water, food and our own bodies. People also can come into contact with radiation through medical procedures, such as X-rays and some cancer treatments. What happens when a human is radioactive?Read More →
There are no side effects directly associated with the injection. Your cat will not experience nausea, hair loss, lethargy, or decreased appetite due to his procedure. However, following treatment, some cats may experience a short period of readjustment as the thyroid levels return to normal. Does radioactive iodine harm myRead More →
Neon, the second-lightest noble gas, has three stable isotopes and no long-lived radioactive isotopes. The stable isotopes, neon-20, neon-21, and neon-22, are present in a ratio of 9048 : 27 : 925 in the atmosphere and in varying compositions in other materials. Is ND 142 radioactive? The radioactive decay ofRead More →
Promethium has no role to play on living things and is slightly dangerous because of its intense radioactivity. Which element is radioactive in lanthanide? Promethium $text{ (Pm) }$ is the only lanthanide that exhibits radioactivity. It is one of the two elements among the first 83 elements. It does notRead More →
Lanthanide and Actinide Series are both referred to as Rare Earth Metals. These elements all have a high diversity in oxidation numbers and all are radioactive. The most common and known element is Uranium, which is used as nuclear fuel when its converted into plutonium, through a nuclear reaction. IsRead More →
