OBJETIVO: Exposições a altos níveis do gás radioativo radônio podem causar câncer de pulmão e, conseqüentemente, o conhecimento da concentração deste gás em ambientes internos é importante, do ponto de vista de proteção radiológica, para a população de um modo geral. Neste trabalho realizaram-se monitorações passiva e integrada de radônio em alguns tipos de ambientes fechados na região da Baixada Santista, SP, tais como túneis, galpão de fertilizantes, "shopping center", lojas de cerâmica e residências, com o objetivo de se avaliar os níveis de concentração existentes nestes locais. MATERIAIS E MÉTODOS: As medidas de concentração de radônio foram realizadas utilizando a técnica do registro de traços de partículas alfa em folhas plásticas de...
