چکیده

Despite its high toxicity, beryllium is widely used because of its unique properties. Beryllium is toxic both as a carcinogen and as the agent that initiates chronic beryllium disease (CBD). CBD, a granulomatous lung disease, is a cellmediated immune response to inhaled beryllium in 6–20% of exposed individuals. Considerable invesitagations into the nature and effects of CBD have been conducted but the role of beryllium in triggering CBD is still not well understood. Most research has focused on the biological and environmental effects of beryllium with far less emphasis on the speciation and interactions of beryllium under physiological conditions. The natural forms of beryllium, beryl and emerald, have not been reported to cause CBD unlike processed forms of beryllium metal and BeO. The beryl structure [Be3Al2(SiO3)6] (Figure 1) is interesting in two

Introduction: Thyroid cancer is at the ninth from ten of common malignant cancer. A man has higher risk to get Thyroid cancer that a woman has. This organ is lain near human neck. The use of radioactive I-131, I-123 and Tc-99m for diagnosis of thyroid cancer has a risk where other organs around Thyroid will accept dose of radiation. One of the risks is large dose which is accep...
