How are isotopes used to keep food from spoiling?
Typically, dehydration and irradiation. The causes of most food spoilage is the growth of bacteria in the moist environment of the food. Irradiation can kill all the bacteria, so as long as the package is sealed, no bacteria can grow there. And dehydration removes most of the water from the food so that it takes up less space and weight, and stays edible for longer times.
Is nobelium radioactive?
Yes, nobelium is radioactive. It is a synthetic element that does not occur naturally and is produced in laboratory settings. All isotopes of nobelium are radioactive and have short half-lives, making them highly unstable.
Why is food sometimes radioactive?
the soil can get radioactive poisining. The plants can then use that soil and absorb the radioactive chemical. It the is in our food and that is that
Why can the effects of radioactive decay on the body be useful and harmful?
Radioactive materials released from a source can affect the human body via a number of pathways. Some may be transported by winds or water to our vicinity. These radioactive substances can affect us through direct irradiation and may be inhaled or ingested.
Which is not a method used to keep microorganisms from spoiling food?
Depending on the type of the food many methods of preservation exist: adding sugar, salting, irradiation with gammas, freezing, lyophilisation, pasteurization etc.
How can be harmful?
Thorium is a radioactive metal. Alpha rays irradiation can be dangerous.
Is irradiation the same as radioactive iodine?
No, irradiation and radioactive iodine are not the same. Irradiation is the process of exposing something to radiation, while radioactive iodine is a form of iodine that emits radiation and is used in medical treatments, such as for thyroid conditions.
How can thorium be harmful?
Thorium is a radioactive metal. Alpha rays irradiation can be dangerous.

How do you use irradiation in a sentence?
He was irradiated from the UV rays after the ozone hole. This is a sentence using irradiation as a word.
How does irradiation preserve food?
Irradiation preserves food by destroying microbes just as heat does in the canning process. In both processes, the food must have been first sealed in a container e.g., a can, jar, or pouch.
Who won the 1938 Nobel Peace Prize in physics?
A native from Italy, Enrica Ferni - for demonstrating the existence of radioactive elements produced for neutron irradiation. Enrico Fermi Italy "for his demonstrations of the existence of new radioactive elements produced by neutron irradiation, and for his related discovery of nuclear reactions brought about by slow neutrons"
How does nuclear chemistry apply to food chemistry?
One method of preservating food is by irradiation.
What are the pros of food irradiation and how do they contribute to food safety and preservation?
Food irradiation is a process that can help kill harmful bacteria and parasites in food, reducing the risk of foodborne illnesses. It can also extend the shelf life of certain foods by slowing down the ripening process and inhibiting the growth of mold and bacteria. Overall, food irradiation can contribute to improved food safety and preservation by reducing the risk of contamination and spoilage.
What technology is the most effective at fighting food-borne bacteria?
irradiation
Is the irradiation safe for food treatment?
Yes, it is safe in controlled conditions.
Is nobelium radioactive?
Yes, nobelium is radioactive. It is a synthetic element that does not occur naturally and is produced in laboratory settings. All isotopes of nobelium are radioactive and have short half-lives, making them highly unstable.
