Radiation Accident In Mexico City
In March–August 1962, a radiation incident in Mexico City occurred when a ten-year-old boy took home an unprotected industrial radiography source. Four people died from overexposure to radiation from a 5- Ci cobalt-60 capsule, an industrial radiography orphaned source that was not contained in its proper shielding. For several days, the boy kept the capsule in his pocket, then placed it in the kitchen cabinet of his home in Mexico City. Having obtained the source on March 21, the boy died 38 days later on April 29. Subsequently, his mother died on July 10; his 2-year-old sister died on August 18, and his grandmother died on October 15 of that year. The boy's father also received a significant dose of radiation; however, he survived. Five other individuals also received significant overdoses of radiation.

Teletherapy Capsule
External beam radiotherapy (EBRT) is the most common form of radiotherapy (radiation therapy). The patient sits or lies on a couch and an external source of ionizing radiation is pointed at a particular part of the body. In contrast to brachytherapy (sealed source radiotherapy) and unsealed source radiotherapy, in which the radiation source is inside the body, external beam radiotherapy directs the radiation at the tumour from outside the body. Orthovoltage ("superficial") X-rays are used for treating skin cancer and superficial structures. Megavoltage X-rays are used to treat deep-seated tumours (e.g. bladder, bowel, prostate, lung, or brain), whereas megavoltage electron beams are typically used to treat superficial lesions extending to a depth of approximately 5 cm (increasing beam energy corresponds to greater penetration). X-rays and electron beams are by far the most widely used sources for external beam radiotherapy. A small number of centers operate experimental and pi ...

List Of Civilian Radiation Accidents
This article lists notable civilian accidents involving radioactive materials or involving ionizing radiation from artificial sources such as x-ray tubes and particle accelerators. Accidents related to nuclear power that involve fissile materials are listed at List of civilian nuclear accidents. Military accidents are listed at List of military nuclear accidents. Scope of this article In listing civilian radiation accidents, the following criteria have been followed: # There must be well-attested and substantial health damage, property damage or contamination. # The damage must be related directly to radioactive materials or ionizing radiation from a man-made source, not merely taking place at a facility where such are being used. # To qualify as "civilian", the operation/material must be principally for non-military purposes. # The event is not an event involving fissile material or a nuclear reactor.

1962 Health Disasters
Year 196 ( CXCVI) was a leap year starting on Thursday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Dexter and Messalla (or, less frequently, year 949 ''Ab urbe condita''). The denomination 196 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * Emperor Septimius Severus attempts to assassinate Clodius Albinus but fails, causing Albinus to retaliate militarily. * Emperor Septimius Severus captures and sacks Byzantium; the city is rebuilt and regains its previous prosperity. * In order to assure the support of the Roman legion in Germany on his march to Rome, Clodius Albinus is declared Augustus by his army while crossing Gaul. * Hadrian's wall in Britain is partially destroyed.
