What is cesium iodide used for?
Caesium Iodide is used to make cell windows and prisms for infrared application up to 50 µm. It is also used in beam splitters for Fourier Transform Infra-Red (FTIR) devices. And in scintillators where it may or may not be doped with Thallium.

Where is cesium naturally found?
Natural abundance Caesium is found in the minerals pollucite and lepidolite. Pollucite is found in great quantities at Bernic Lake,Manitoba, Canada and in the USA, and from this source the element can be prepared.

Is Cesium 137 a beta emitter?
Caesium 137 is a radioactive element with a relatively long half-life of 30.15 years. This particular isotope of caesium is both a beta and gamma emitter. It is produced in some abundance by fission reactions.
Why is Caesium 137 so dangerous?
Cesium-137 is an especially dangerous fission product because of its high yield during fission, moderate half-life, high-energy decay pathway, and chemical reactivity. Because of these properties, cesium-137 is a major contributor to the total radiation released during nuclear accidents.
What does cesium-137 do to the human body?
External exposure to large amounts of Cs-137 can cause burns, acute radiation sickness, and even death. Exposure to Cs-137 can increase the risk for cancer because of exposure to high-energy gamma radiation.
How long will it take for all the cesium-137 to decay into barium 137?
Cesium-137 emits beta particles as it decays to the barium isotope, Ba-137m (half life = 2.6 minutes). How are people exposed to cesium-137?
What is the most dangerous radioactive isotope?
strontium-90
Why do gamma rays have no charge?
Thus gamma rays have no mass and no charge. It can get rid of this energy by emitting a pulse of very high frequency electromagnetic radiation, called a gamma ray. -particles and -particles pull electrons off atoms as they pass (we say the ionise the atoms), but rays don’t.
Is cesium poisonous or hazardous?
Nonradioactive caesium compounds are only mildly toxic, but the pure metal’s tendency to react explosively with water means that caesium is considered a hazardous material, and the radioisotopes present a significant health and ecological hazard in the environment.
What happens if you eat cesium?
HIGHLIGHTS: Exposure to stable or radioactive cesium occurs from ingesting contaminated food or drinking water or breathing contaminated air. High levels of radioactive cesium in or near your body can cause nausea, vomiting, diarrhea, bleeding, coma, and even death.
Is cesium found in the human body?
Humans may be exposed to cesium by breathing, drinking or eating. In air the levels of cesium are generally low, but radioactive cesium has been detected at some level in surface water and in many types of foods.
Why is strontium 90 dangerous to humans?
The harmful effects of strontium-90 are caused by the high energy effects of radiation. Since radioactive strontium is taken up into bone, the bone itself and nearby soft tissues may be damaged by radiation released over time.
Does strontium cause cancer?
Exposure to high levels of radioactive strontium may cause cancer. Leukemia has been seen in humans exposed to relatively large amounts of radioactive strontium. Leukemia and cancers of the bone, nose, lung, and skin have also been seen in laboratory animals.
How long will it take until only 25 percent of the strontium-90 remains?
It takes 28.8 years for half of the strontium to decay to 50 grams. This is called one half-life. After 28.8 more years, strontium-90 has decayed to 25 grams.
How long does it take for strontium-90 to decay?
29 years
How long will it take for 10 grams of carbon 14 to decay to 2.5 grams?
5730 years
How many half lives is equivalent to 100 years?
two half lives
Is nickel highly radioactive?
There are five naturally occurring isotopes of nickel: nickel-58, nickel-60, nickel-61, nickel-62, and nickel-64. Isotopes are two or more forms of an element. Seven radioactive isotopes of nickel are known also. A radioactive isotope is one that breaks apart and gives off some form of radiation.
What does the 59 mean in nickel 59?
Nickel-58
Why is nickel named after the Devil?
Nickel’s name comes from the Saxon term ‘Kupfernickel’ or Devils’ Copper. 15th century miners in Germany found a brown-red ore which they believed to contain copper. They called it Kupfernickel or Devils’ Copper because they couldn’t recover copper from it. Coins in the USA first used nickel alloyed with copper in 1857 …
