For treatment of patients with cancer, radiation oncology is a common treatment to help fight and treat the cancerous region. One of the side effects of radiation therapy is a progressive stiffening of the tissues under radiation. The more radiation a tissue receives, the more likely the stiffening will occur; and patients with long treatment schedules or on a second round of radiation often see these effects. This stiffening is usually treated with stretching to the affected areas.
For head and neck cancer patients, if radiation is applied to areas around the mouth and jaw, the stiffening of the facial tissues causes trismus. Trismus is the limited opening (or range-of-motion) of the mouth. Severe cases of trismus are often called "lockjaw." Unfortunately, the mouth does not easily lend itself to be stretched open, and the stiffening is significant. Additionally, patients are rarely warned of this side-effect to prevent it. Patients often only discover it after the stiffening has caused limitations in their ability to eat, drink, speak, etc.
Exercises and stretching to prevent trismus is the best course when head-and-neck cancer patients are receiving radiation therapy. However, treatment for stiffening of the jaw or trismus includes heat, medication and stretching. Stretching the jaw is difficult and a number of aids have been developed to assist patients, like the OraStretch Press or the TheraBite systems. These devices are used by patients to press their mouth open and stretch the jaw and facial muscles, to overcome the stiffening caused by radiation.
Nausea and vomiting are most likely to occur when the radiation dose is high or if the abdomen or another part of the digestive tract is irradiated
Vascular malformations can potentially occur many years after radiation therapy to the brain. Additionally, it is also assumed that severe or repeated head trauma can cause cerebral capillaries to bleed.
Surgical therapy can be both disfiguring and disabling. Many normal tissues can be adversely affected by radiation therapy. Side effects that commonly occur shortly after a treatment cycle include nausea, vomiting, fatigue, loss of.
Radiation can occur in a vacumn.
Pigs is the answer.
It can occur through conduction, convection and radiation.
Radiation exposure safety is the process of preventing or minimizing exposure to radiation, and tracking what does occur.
No, radiation occurs mainly between gases!
Thermal radiation is emitted by the red hot heating element.
Yes, if its on.
Radiation is the only type of heat transfer that can occur through vacuum (space with no particles).
Radiation, for one.
If you are exposed to it too long.
When skies are clear
While radiation symptoms can occur from a single, prolonged, exposure, the symptoms of radiation are not contagious.
The exposure to nuclear radiation has many risks associated with it. Cancer, DNA mutations, and radiation poisoning can all occur with any level of radiation exposure.
It can occur in a vacuum. For instance, heat arrives from the sun as radiation.
No, Convection does not occur in the Core. For example, in the Sun, the convection occurs only after the Radiation zone. In the radiation zone the energy is transported by radiation (ie, by photons). At about 0.8 solar radius the density and temperature are not enough to transport the energy by radiation, so convection sets in.
