Berylliosis is a lung disease caused by exposure to beryllium, a toxic metal. Beryllium is used in certain industrial applications, including some older microwave magnetrons.
While I can understand your concerns, it's important to note that the risk of developing berylliosis from the magnetrons you mentioned is generally considered to be low. Beryllium exposure is typically associated with long-term occupational exposure in industries where beryllium is actively processed or handled.
That being said, it's always important to take precautions when handling potentially hazardous materials or substances. If you're worried about potential exposure, it's advisable to consult a healthcare professional who can evaluate your specific situation and provide appropriate advice based on your symptoms, medical history, and potential exposure.
It's worth noting that the magnets inside the magnetrons are not likely to contain beryllium, as they are usually made of other materials like neodymium or ferrite. Nonetheless, if you have any concerns about your health or exposure to hazardous substances, seeking professional medical advice is the best course of action.
