The sources can be also lost and mishandled, as in the Goiânia accident, during which several people had external beta burns and more serious gamma burns, and several died. Numerous accidents also occur during radiotherapy due to equipment failures, operator errors, or wrong dosage. Electron beam sources and particle accelerators can be also sources of beta burns. The burns may be fairly deep and require skin grafts, tissue resection or even amputation of fingers or limbs. Treatment
Radiation burns should be covered by a clean, dry dressing as soon as possible to prevent infection. Wet dressings are not recommended. The presence of combined injury (exposure to radiation plus trauma or radiation burn) increases the likelihood of generalized sepsis. This requires administration of systemic antimicrobial therapy.

In this situation, the stress to the joint surface is not even and can cause some form of osteochondrosis in the elbow when the puppy grows or make already existing elbow dysplasia even worse. Some of the breeds that are susceptible to that are for example Dachshunds, Corgis, Pugs, Bulldogs, and Beagles. Signs and symptoms
These conditions nearly all present with an insidious onset of pain referred to the location of the bony damage. Some, notably Kienbocks disease of the wrist, may involve considerable swelling, and Legg-Calvé-Perthes disease of the hip causes the victim to limp. The spinal form, Scheuermanns disease, may cause bending, or kyphosis of the upper spine, giving a "hunch-back" appearance. Symptoms in animals
The most common symptoms are lameness and pain in the affected joints. Animals may try to ease the pain and walk differently and the pain can be noticed by the change in animals walking style. The condition affects both sides (right and left leg). On most occasions, the other leg is worse. This can result that the dog starts encumbering the other leg and the healthier leg becomes more strained. Sometimes the symptoms are so mild or there are no symptoms which can make it hard to detect that there is something wrong with that dog. Cause
The ultimate cause for these conditions is unknown, but the most commonly cited cause factors are rapid growth, heredity, trauma (or overuse), anatomic conformation,  and dietary imbalances; however, only anatomic conformation and heredity are well supported by scientific literature.
