This event is one of several notable radiation accidents and incidents involving radiotherapy equipment, highlighting the potential dangers of ionizing radiation when safety protocols are not strictly followed.

Background[edit | edit source]

Radiotherapy is a medical treatment that uses high doses of radiation to kill cancer cells and shrink tumors. While it is a critical component of cancer treatment, the equipment used in radiotherapy must be carefully calibrated and monitored to ensure patient safety. The San Juan de Dios radiotherapy accident underscores the importance of these safety measures.

The Accident[edit | edit source]

In 1996, a tragic error occurred at the San Juan de Dios Hospital involving a Cobalt-60 therapy unit, a common type of equipment used in radiotherapy. The accident was caused by a series of mistakes in the calibration and operation of the radiotherapy machine. As a result, several patients received overdoses of radiation during their treatment.

The exact number of patients affected and the full scope of the consequences were initially difficult to ascertain. However, it was later revealed that the overdoses led to severe health complications for many patients, including radiation burns and an increased risk of secondary cancers. The incident not only had devastating effects on the patients and their families but also raised significant concerns about the safety protocols and regulatory oversight of radiotherapy equipment.

Aftermath[edit | edit source]

Following the accident, there was an immediate response from both the Costa Rican government and international health organizations. Investigations were launched to determine the causes of the accident and to identify measures to prevent similar incidents in the future.

One of the key outcomes of the investigation was the recognition of the need for stricter safety protocols and regular equipment checks in medical facilities using radiation therapy. Additionally, the accident highlighted the importance of proper training for personnel operating radiotherapy equipment.

Impact[edit | edit source]
