El radón es un elemento químico perteneciente al grupo de los gases nobles. En su forma gaseosa es incoloro, inodoro e insípido y en forma sólida su color es rojizo. En la tabla periódica tiene el número 86 y símbolo Rn. Su masa media es de 222, lo que implica que por término medio tiene 222-86 = 136 neutrones. Igualmente, en estado neutro le corresponde tener el mismo número de electrones que de protones, esto es, 86. Es un elemento radiactivo y gaseoso, encuadrado dentro de los llamados gases nobles. El radón es producto de la desintegración del radio (226Ra), elemento altamente radiactivo. El isótopo 219Rn es producto de la desintegración del actinio, llamado actinón y tiene una semivida de 4 segundos.Además de todos estos, el radón tiene 22 isótopos artificiales, producidos por reacciones nucleares por transmutación artificial en ciclotrones y aceleradores lineales. El isótopo más estable es el 222Rn, también el más abundante, con una semivida de 3,8 días y producto de la desintegración del 226Ra. Al emitir partículas alfa se convierte en 218Po.
