What is beta decay used for
How is beta decay used in the real world?
Beta decay is used in medicine, manufacturing, and to study particle physics. Beta decay can be used in medicine as a radioactive tracer.
Why is beta decay important?
Beta decays tend to allow the nucleus to approach the optimal proton/neutron ratio. When there are too many neutrons related to the protons, negative beta decay occurs; when there are too many protons related to the neutrons, positive beta decay takes place.
How is beta decay used in manufacturing?
Beta rays have a number of important uses in industrial processes. Since they can pass through some materials, they are used to gauge the thickness of films of material coming off production lines such as paper and plastic film. A similar process checks the integrity of sewn seams in textiles.
What can gamma decay be used for?
Gamma rays are ionizing electromagnetic radiation, obtained by the decay of an atomic nucleus. Gamma rays are more penetrating, in matter, and can damage living cells to a great extent. Gamma rays are used in medicine (radiotherapy), industry (sterilization and disinfection) and the nuclear industry.
Does beta decay add a proton?
In beta decay, one of the neutrons in the nucleus suddenly changes into a proton, causing an increase in the atomic number of an element.
How is alpha decay used in everyday life?
It is used in the treatment of skeletal metastases (cancers in the bones). Alpha decay can provide a safe power source for radioisotope thermoelectric generators used for space probes and were used for artificial heart pacemakers. Alpha decay is much more easily shielded against than other forms of radioactive decay.
How do scientists use gamma rays?
Scientists can use gamma rays to determine the elements on other planets. The Mercury Surface, Space Environment, Geochemistry, and Ranging (MESSENGER) Gamma-Ray Spectrometer (GRS) can measure gamma rays emitted by the nuclei of atoms on planet Mercury’s surface that are struck by cosmic rays.
How do doctors use gamma rays?
However, gamma rays can also be used to treat cancer. Radiation therapy, or radiotherapy, uses high-energy gamma rays to kill cancer cells and shrink tumours. Gamma Knife Radiosurgery is a special form of radiotherapy. It uses beams of gamma rays to treat injured brain tissue by damaging the DNA of dangerous cells.
Why are gamma rays not used for medical imaging?
Imaging with gamma rays is used in nuclear medicine, as well as in court medicine.

Who discovered microwave rays?
Humanity’s understanding of the universe took a giant leap forward 50 years ago today. On May 20, 1964, American radio astronomers Robert Wilson and Arno Penzias discovered the cosmic microwave background radiation (CMB), the ancient light that began saturating the universe 380,000 years after its creation.
What are microwaves used for?
Microwaves are widely used in modern technology, for example in point-to-point communication links, wireless networks, microwave radio relay networks, radar, satellite and spacecraft communication, medical diathermy and cancer treatment, remote sensing, radio astronomy, particle accelerators, spectroscopy, industrial …
What animals can see gamma rays?
None known to date. The species with the widest known visible range is the mantis shrimp that can see into the UV range and down into the far infrared…
Is microwave radiation harmful?
Microwaves are different from radio waves and X-rays. X-rays are ionizing radiation, which means they can alter atoms and molecules and damage cells. Ionizing radiation is harmful to your body. But the non-ionizing radiation used by microwaves isn’t harmful.
How is microwave radiation detected?
Currently, microwave power can be detected using a device called bolometer. A bolometer usually consists of three materials: Electromagnetic absorption material, a material that converts electromagnetic waves into heat, and a material that converts the generated heat into electrical resistance.
How far away from microwave is safe?
approximately 2 inches
A Federal standard (21 CFR 1030.10) limits the amount of microwaves that can leak from an oven throughout its lifetime to 5 milliwatts (mW) of microwave radiation per square centimeter at approximately 2 inches from the oven surface. This limit is far below the level known to harm people.
What material should you never put in your microwave?
The most commonly-used household item you should never put in the microwave is aluminum foil. It’s essentially very thin metal which, when exposed to microwave radiation, will reflect the energy instead of absorbing it. This, in turn, can create sparks that could ruin the appliance, or worse, start a fire.
Does microwaving destroy nutrients?
However, microwave cooking is actually one of the least likely forms of cooking to damage nutrients. That’s because the longer food cooks, the more nutrients tend to break down, and microwave cooking takes less time.
What has more radiation microwave or cell phone?
It should be noted that microwave ovens emit 700 Watts of power, hundreds of times more than the maximum that a cell phone does (and thousands of times more than your cell phone does during the majority of your call).
What will explode in a microwave?
Exploding foods:
potatoes (unless you poke holes before cooking) shelled eggs. tomatoes and tomato sauce. lemons.
Can you put toilet paper in the microwave?
Parchment paper: Parchment paper is designed for oven use, so you can microwave them without much risk. Tissue paper: Sanitary napkins, facial tissue and toilet paper are a big no. The paper is very thin and can catch fire easily when exposed to extreme heat.
What 3 things are microwaves attracted to?
Microwaves are attracted to fat, sugar, and water molecules. Microwaves cause molecules to vibrate.
