Does irradiation affect quality?
“Quality of food is related to dose of irradiation. It takes a very high dose to see damage to quality. At levels that destroy E. coli and Salmonella, there is no effect on quality. In general, vitamin loss during food irradiation turns out to be less than with heat processing.

Working Principle of Irradiation Therapy
Irradiation therapy can be of benefit for the cancer patient in three different ways:
Possible Side Effects of Irradiation Therapy
The word "irradiation" can invoke fear among patients. However, the fears many people have about irradiation therapy are largely unfounded. During treatment a certain proportion of healthy cells is always affected by the irradiation, however, the damage is recovered in the vast majority of cases.
How we can help you in fighting against cancer

How is radiation given?
Radiation therapy can be given in 3 ways: 1 External radiation (or external beam radiation): uses a machine that directs high-energy rays from outside the body into the tumor. It’s done during outpatient visits to a hospital or treatment center. It's usually given over many weeks and sometimes will be given twice a day for several weeks. A person receiving external radiation is not radioactive and does not have to follow special safety precautions at home. 2 Internal radiation: Internal radiation is also called brachytherapy. A radioactive source is put inside the body into or near the tumor. With some types of brachytherapy, radiation might be placed and left in the body to work. Sometimes it is placed in the body for a period of time and then removed. This is decided based on the type of cancer. Special safety precautions are needed for this type of radiation for a period of time. But it's important to know if the internal radiation is left in the body, after a while it eventually is no longer radioactive. 3 Systemic radiation: Radioactive drugs given by mouth or put into a vein are used to treat certain types of cancer. These drugs then travel throughout the body. You might have to follow special precautions at home for a period of time after these drugs are given.
What is systemic radiation?
Systemic radiation: Radioactive drugs given by mouth or put into a vein are used to treat certain types of cancer. These drugs then travel throughout the body. You might have to follow special precautions at home for a period of time after these drugs are given.
What is the treatment for cancer that has returned?
To treat cancer that has returned (recurred) If a person's cancer has returned (recurred), radiation might be used to treat the cancer or to treat symptoms caused by advanced cancer. Whether radiation will be used after recurrence depends on many factors.
How does radiation help cancer cells?
But cancer cells grow and divide faster than most normal cells. Radiation works by making small breaks in the DNA inside cells. These breaks keep cancer cells from growing and dividing and cause them to die.
Why do people get radiation to their head?
This is done to help prevent cancer from spreading to the head even before it can.
How many people with cancer get radiation?
More than half of people with cancer get radiation therapy. Sometimes, radiation therapy is the only cancer treatment needed and sometimes it's used with other types of treatment. The decision to use radiation therapy depends on the type and stage of cancer, and other health problems a patient might have.
What is the best treatment for cancer?
Radiation may be used by itself in these cases to make the cancer shrink or completely go away. In some cases, chemotherapy or other anti-cancer drugs may be given first. For other cancers, radiation may be used before surgery to shrink the tumor ...
What is the purpose of irradiating food?
Irradiation can serve many purposes. Prevention of Foodborne Illness – to effectively eliminate organisms that cause foodborne illness, such as Salmonella and Escherichia coli ( E. coli ). Preservation – to destroy or inactivate organisms that cause spoilage and decomposition and extend the shelf life of foods.
What is the purpose of irradiating tropical fruits?
Control of Insects – to destroy insects in or on tropical fruits imported into the United States. Irradiation also decreases the need for other pest-control practices that may harm the fruit. Delay of Sprouting and Ripening – to inhibit sprouting (e.g., potatoes) and delay ripening of fruit to increase longevity.
Why sterilize food?
Sterilized foods are useful in hospitals for patients with severely impaired immune systems, such as patients with AIDS or undergoing chemotherapy. Foods that are sterilized by irradiation are exposed to substantially higher levels of treatment than those approved for general use.
What is the FDA requirement for irradiated foods?
The FDA requires that irradiated foods bear the international symbol for irradiation. Look for the Radura symbol along with the statement “Treated with radiation” or “Treated by irradiation” on the food label. Bulk foods, such as fruits and vegetables, are required to be individually labeled or to have a label next to the sale container.
Why do we need to store irradiated food?
Irradiated foods need to be stored, handled, and cooked in the same way as non-irradiated foods, because they could still become contaminated with disease-causing organisms after irradiation if the rules of basic food safety are not followed.
How does ionizing radiation affect food?
Food irradiation (the application of ionizing radiation to food) is a technology that improves the safety and extends the shelf life of foods by reducing or eliminating microorganisms and insects.

What is gamma radiation?
There are three sources of radiation approved for use on foods. Gamma rays are emitted from radioactive forms of the element cobalt (Cobalt 60) or of the element cesium (Cesium 137). Gamma radiation is used routinely to sterilize medical, dental, and household products and is also used for the radiation treatment of cancer.
I want to use irradiation as a phytosanitary treatment to import a commodity. Where do I start?
APHIS must first approve the importation of the fresh fruit or vegetables into the United States.
I checked FAVIR. The commodity is eligible for importation, but irradiation is not listed as an approved treatment. What do I do?
If the commodity is eligible for entry and does not require any treatment for importation, irradiation is not required, and you may apply for an import permit. If you have questions about the import permit process, please contact:
Are there non-phytosanitary import requirements that I should know about?
Federal agencies other than APHIS have regulatory oversight on importations of food items into the United States. In advance of importation, contact the agencies below for additional information:
I would like APHIS to certify an irradiation facility to apply phytosanitary irradiation treatments to fresh fruits and vegetables. Where can I get more information?
For more information concerning the approval process for facility certification contact:
Does UV light kill bacteria?
No resistance of microorganisms to UV irradiation has been reported, and multi-antibiotic resistant strains are as susceptible as their wild-type counterparts. Low and mild doses of UV kill microorganisms by damaging the DNA, while any DNA damage in host cells can be rapidly repaired by DNA repair enzymes.
Can UBI be used for septicemia?
However the use of UBI to treat septicemia cannot be solely due to UV-mediated killing of bacteria in the blood-stream, as only 5-7% of blood volume needs to be treated with UV to produce the optimum benefit.
Why do people need palliative radiation?

How is palliative radiation delivered?
There are three ways to deliver radiation therapy, including palliative radiation therapy: External-Beam Radiation Therapy: This type of radiation is delivered to the outside of the body by a special radiation machine. Internal Radiation Therapy: Internal radiation is delivered by radioactive material placed inside the body near the tumor.
How long does it take for radiation side effects to go away?
Most side effects of palliative radiation therapy will resolve within weeks of the last radiation treatment.
How is radiation delivered?
Internal Radiation Therapy: Internal radiation is delivered by radioactive material placed inside the body near the tumor. Systemic Radiation Therapy: Systemic radiation is delivered throughout the body via the bloodstream. An example of this is radioactive iodine that is used to treat certain types of thyroid cancers.
