Episode 515: The radioactive decay formula Here‚ the key idea is the random nature of the decay. Avoid simply pulling pull equations out of the air – at least make them plausible. Summary Discussion: The meaning of the decay constant λ. (15 minutes) Discussion: The link with half-life. (15 minutes) Student experiments: Analogue experiments linking probability with decay rates. (20 minutes) Discussion: The meaning of the decay constant λ. Start from the definition

Austin Dobrzynski Chem 1 10/11/14 Copper Ch. 3 Isotope Paper Copper In humans‚ copper is essential to the proper functioning of organs and metabolic processes. The human body has a complex homeostatic mechanism that lets us supply copper‚ while eliminating excess copper whenever this occurs. The dietary standards for copper have been set by various health agencies around the world. Standards adopted by some nations recommend different copper intake levels for adults

Radioactive Isotopes Radioactive Isotopes Medical isotopes are used in medicine in three distinct ways: 1. Radioactive isotopes can be injected into a patient‚ and their emitted energy can then be captured on film. The resulting image is an important diagnostic tool. 2. Gamma rays emitted from a radioactive source can be directed onto a tumour‚ destroying the cancerous cells. 3. Radioactive isotopes can be manufactured into drugs. Once injected into a patient‚ the drug will

In the song “Radioactive” by Imagine dragons is about a time in prison with hard physical labor. The song has more than just one meaning‚ one is the hard physical labor of a prisoner and the second one is an uprising getting back into reality from prison. At the beginning stanza of the song the lead vocalist Dan Reynolds sing “ I wipe my brow and sweat my rust” (Line 6) which means very hard physical labor and abuse from instructions or other personals. This line means a lot to people who have been

Modern Gaming Brief History Gaming has changed a lot in the past few years‚ from whole games being developed by a three to five man teams usually consisting of a programmer‚ designer and an artist to near a dozen programmers and close to a hundred artists. When did we make this huge leap? Gamers often agree that this development happen somewhere around 1995 to 97‚ just as 3d games where surfacing and becoming playable. 3d games have excited since the late 80s‚ when referring to 3d games I’m referring

All kinds of rocks contain very small amounts of radioactive elements‚ these are unstable and they break down into more stable atoms over time‚ which is called radioactive decay. Scientists can tell how old a rock is by using radiometric clocks‚ or by looking at its absolute age. Geologists measure the amount of certain radioactive elements; as time passes the radioactive elements change at regular rates‚ into non-radioactive elements. The older a rock is the larger the number of elements. The age

Alpha‚ beta and gamma radiation The degree to which each different type of radiation is most dangerous to the body depends on whether the source is outside or inside the body. If the radioactive source is inside the body‚ perhaps after being swallowed or breathed in: Alpha radiation is the most dangerous because it is easily

Title To determine the half-life of beer foam Purpose In this experiment‚ we will make the bear foam as much as possible by pouring fast and using warm beer and try to estimate the half-life of beer foam based on the changing of height while the foam is collapsing. Theory A quantity is said to be subject to exponential decay if it decreases at a rate proportional to its value. Symbolically‚ this process can be expressed by the following differential equation‚ where N is the quantity and λ (lambda)

the people and wild life around it. In the film Radioactive Wolves‚ I learned about the return of nature and animals to the devastated “Zone” that encompasses the 11‚000 sq. ft. area that was affected by the meltdown of the Chernobyl nuclear plant in 1986. Researchers found that the wolfs were coming back into the "Zones" and found the other animals were to. They wanted to know why and how so they sent researchers in the "Zone" to
