Radon melting point
Radon is a colorless, odorless, and tasteless gas and therefore is not detectable by human senses alone. At standard temperature and pressure, it forms a monatomic gas with a density of 9.73 kg/m , about 8 times the density of the Earth's atmosphere at sea level, 1.217 kg/m . It is one of the densest gases at room temperature and is the densest of the noble gases. Although colorless a… Web11 de abr. de 2024 · In the present paper, an investigation on the natural and anthropic radioactivity and heavy metals content in a basalt aggregate for concrete from Sicily, Southern Italy, was performed as a case study.
