A report from Johns Hopkins University says that patients, following radiation, must be made aware that they can pass along radiation to others. But unlike cholesterol, this subject is rarely, if ever, discussed at the dinner table. The problem is that nuclear diagnostic tests are not going to go away or decrease. Rather, unless we develop other means of diagnosis, these tests will increase in the years ahead.
are treated by brachytherapy. During this procedure, radioactive pellets are inserted into prostate tissue. These tiny pellets, about the size of a grain of rice, are placed around and into the tumour.
But it's still another story if doctors implant permanent brachytherapy implants. These gradually degrade over time and require greater precautions. Radiation experts say patients should not hug family members, or others who want to wish them well, for a few days following implantation. And for six months they should keep six feet away from children and pregnantToday radioactive iodine is also used to treat hyperthyroidism (an overactive thyroid) and thyroid malignancy. In this situation, for the first week after treatment, the patient must sleep alone, use separate towels, dishes and wash clothes separately.
Dr. Gifford Jones' common sense based medical column, offered with the occasional dash of humour, has been published in Canadian newspapers for 30 years.
Can radiation treatment hurt others
Internal radiation is another matter, especially when patients with prostate cancer Pink Adidas Neo
Patients must also remember, but are often not told, about this important fact. Long after they can safely make contact with others, residual radiation in their body can set off sensitive alarm systems.
Nor do patients often know how much radiation they're receiving from common diagnostic procedures. In fact, even the doctors who order these tests often have no idea of the radiation exposure to patients. Or if asked how much radiation is received, grossly underestimate the amount of exposure.
How careful do patients have to be following nuclear diagnostic tests, or after radiation for the treatment of cancer? How long do these nuclear materials remain in the body? And how long will this radiation remain detectable and transmissible to others?
never forgets. This means that radiation is accumulative, each radiation exposure adding to the last one. I've argued we should all have a radiation card outlining our exposure over a lifetime. But so far no one is listening.
Following a bone or thyroid scan the body emits radioactivity that can be detected for up to three days. Scans of the heart can set Adidas Los Angeles Women's Review

There are also varying degrees of radiation. For instance, radiation therapy delivers much higher amounts of radioactivity than nuclear scans. But patients having external radiation therapy should know that beams of radiation focused on a cancer, will not spread radiation to other people.
During scans to detect thyroid disease, coronary troubles and cancer, radioactive drugs are either injected, taken orally or inhaled. Gamma cameras or positron emission tomography (PET) scanners can then detect this energy and use it to produce images of the body on a computer.
Because of this exposure to radiation, doctors advise patients to be certain to wash hands well after using the toilet. And that it's also important to flush the toilet twice to get rid of any radioactive material.
off an alarm for up to 51 days and following iodine therapy this can occur for three months.
But how often are patients advised that they are radioactive? The Journal of Nuclear Medicine recently reported that Adidas Y3 Qasa Primeknit a survey of 66 healthcare facilities revealed that often patients had no idea they were emitting radiation.
The Johns Hopkins report says that if low dose temporary pellets are used, patients require a hospital stay. During this time they should have limited contact with family members. Friends should stay for only 10 to 30 minutes and pregnant women should stay away.
For instance, a survey showed that 94% of pediatricians who ordered a CT scan were unaware of the radiation exposure received by children. They did not know that because children's organs were more sensitive, a single CT scan of the stomach is equivalent to more than 4,000 x rays. In effect, children were often being exposed to levels of radiation that are believed to cause cancer.
