To detect the alpha particles only, a spark detector 6 is used because it is insensitive to the γ and x-rays also given off by the 241Am source.

For example, alpha particles are given off by radionuclides such as uranium-238, radium-226, and other members of the naturally occurring uranium, thorium and actinium decay series which are present in varying amounts in nearly all rocks, soils, and water.

Uranium has 14 known isotopes, all of which are radioactive. Nuclei undergoing nuclear decay release various kinds of emissions. We will discuss three of these emissions: alpha particles, beta particles, and gamma rays.

Alpha particles lack the energy to penetrate even the outer layer of skin, so exposure to the outside of the body is not a major concern. The ionizations they cause are very close together – they can release all their energy in a few cells. This results in more severe damage to cells and DNA.

The entire human body can probably absorb up to 200 rads acutely without fatality. However, as the whole-body dose approaches 450 rads the death rate will approximate 50%, and a total whole-body dose of greater than 600 rads received in a very short time will almost certainly be fatal.

Since radiation therapy is focused on one area of your body, you may experience fewer side effects than with chemotherapy. However, it may still affect healthy cells in your body. Side effects of radiation may include: digestive issues like nausea, vomiting, stomach cramps, diarrhea.

Appetite: While it is important to try not to lose weight during treatment, the side effects of radiation to certain areas of the body may make it difficult to eat and digest. Try eating small meals often, and avoid extremely hot or cold foods.

Radiation is most often given to just one part of the body, so the whole immune system isn’t damaged by it. Still, depending on the dose and the part of the body being treated with radiation, the skin or mucous membranes may be damaged, so you’re less able to keep germs out.

But cancer itself — along with side effects from treatments such as chemotherapy, radiation, and surgery — can significantly impact your appetite, eating habits, activity levels, and weight.

Foods to avoid or reduce during radiation therapy include sodium (salt), added sugars, solid (saturated) fats, and an excess of alcohol. Some salt is needed in all diets. Your doctor or dietitian can recommend how much salt you should consume based on your medical history.

Opt for soft bras with wide straps: if you are undergoing upper body radiation, you may find your bras to be uncomfortable during radiation. Bras with wide straps and no underwire won’t dig into or rub against your skin and breathable fabrics will allow for optimal comfort.

Will I be able to drive after my radiotherapy treatment? Almost all patients are able to drive while receiving radiotherapy treatment. However, with some types of cancer, driving may NOT be recommended due to fatigue or strong pain medication.

Alcohol during radiotherapy Usually it is fine to have small or moderate amounts of alcohol during your treatment. But alcohol can inflame a sore mouth or throat if you are having radiotherapy to your head or neck area. It can also irritate your bladder if you are having pelvic radiotherapy.

Any radiation therapy that is transient, including external beam radiation or brachytherapy that is removed, poses no risk to family members. For these types of therapy, patients are exposed to radiation only during active treatment, and radiation is not carried on the patient’s body.

Radiation generally won’t affect your ability to work: most people only have mild fatigue. For the greatest effectiveness from radiation therapy, once you start your treatment, it’s essential to keep to a continuous schedule.

A naturally occurring compound found in many fruits and vegetables as well as red wine, selectively kills leukemia cells in culture while showing no discernible toxicity against healthy cells, according to a study by researchers at the University of Pittsburgh School of Medicine.

The protective effects of wine were strongest among women with diffuse large B-cell lymphoma, the most common type of non-Hodgkin’s lymphoma. Women with this type of cancer who drank more than six glasses of wine a month were about 60% less likely to relapse or die within five years, compared with non-wine drinkers.

The investigators found that only one percent of wine drinkers had significant colorectal polyps, compared with 18 percent of beer or grain-based liquor drinkers, and 12 percent of those who abstain. The results were statistically significant.

The key findings are that alcohol consumption appears to lower the risk of several types of lymphoma and plasma cell neoplasms, but has little effect on the risk of myeloid tumours such as acute myeloid leukaemia.

SMOKING cigarettes may increase a person’s risk of contracting leukemia by 30 percent and cause up to 3,600 cases of adult leukemia a year in the United States, according to a new analysis.

This is a common symptom that people with CLL usually notice first. The enlarged lymph nodes are not usually painful. Discomfort or fullness in the upper left part of the abdomen, caused when the spleen increases in size. Symptoms often called “B symptoms” that include fever, chills, night sweats, and weight loss.

However, evidence is accumulating that alcohol consumption is associated with increased risks of melanoma and of prostate and pancreatic cancers (4, 15). Alcohol consumption has also been associated with decreased risks of kidney cancers (16–18), and non-Hodgkin lymphoma (19, 20) in multiple studies.
