Gamma radiation doesn't change the food in any way; it merely removes bacteria so thoroughly that the food keeps fresh as long as it stays sealed. Normal "uncontaminated" food contains enough bacteria that they will eventually grow into a large population and rot the food.

Why food stays fresher longerafter it has been exposed to gamma radiation?

Gamma radiation can kill microorganisms and pests that cause food spoilage, thus extending its shelf life. Additionally, gamma radiation can break down enzymes that cause ripening, slowing down the spoilage process. Overall, gamma radiation reduces microbial growth and enzymatic activity, keeping the food fresher for a longer period.


What process that uses gamma rays to eliminate harmful bacteria in meat and poultry?

Gamma rays have extremely high energies, and seeing as they are a form of ionizing radiation, they can cause cellular damage. When gamma rays are aimed at bacteria, in much the same as radiation harms humans, DNA damage occurs eventually resulting in the death of cells.


What are the purpose of gamma radiation?

Gamma radiation is often used in various industries for sterilizing medical equipment and food, treating cancer, and preserving food. It is also used in some imaging techniques, such as PET scans. Additionally, gamma radiation is used in research and development in fields like physics and chemistry.


How radioactivity is applicable in food preservation?

Food may be exposed to radiation to kill potential infectious agents.


What type of radiation is used to sterilize food?

Ionizing radiation, most commonly gamma rays or electron beams, is used to sterilize food. This process disrupts the DNA or RNA of microorganisms in the food, preventing their growth and proliferation.


What are Gamma particles in chemistry?

Gamma particles are high-energy electromagnetic radiation emitted during nuclear reactions. They have the shortest wavelength and highest frequency among types of electromagnetic radiation. These gamma rays are commonly used in medical diagnostics and treatments, as well as in industrial applications such as sterilization and food preservation.


What were people exposed to during the atomic bombings of Hiroshima and Nagasaki?

Radiation, loss of houses and food.


What does irradiation use?

Irradiation uses high-energy rays, such as gamma rays, X-rays, or electron beams, to kill bacteria and other pathogens in food products. This process helps to extend the shelf life of the food and reduce the risk of foodborne illnesses.


Do microwave ovens emit gamma rays?

No, microwave ovens do not emit gamma rays. They emit non-ionizing radiation in the form of microwaves, which are a type of electromagnetic radiation that heats food by causing water molecules to vibrate, generating heat. These microwaves are specifically tuned to be absorbed by water, fats, and sugars in food.


Can photosynthesis work when there is no light?

No it can't Yes it can, with a broad definition of 'light'. There exist a fungus that grows inside the chernobyl ruins that has so much melanin in it, it is nearly black. The melanin can absorb the radioactive (gamma) radiation that is abundant there, converting it to food, the same way chlorophyll captures light (which is just radiation with a much lower frequency than gamma radiation) and converts it to food.


What are three uses of gamma rays?

Three uses of gamma rays are in cancer treatment (radiation therapy), sterilization of medical equipment and food, and non-destructive testing in industries such as aerospace and automotive.


How can radiation be used to preserve food?

Radiation can be used to preserve food by killing microorganisms and insects that cause food spoilage. This can be done using ionizing radiation such as gamma rays or X-rays to disrupt the DNA of these organisms, preventing them from reproducing. The process can extend the shelf life of food by inhibiting bacterial growth and delaying ripening.
