Riscos para a saúde humana da exposição cotidiana a radiações eletromagnéticas: o uso de telefones celulares como exemplo

Emerson Sales (Instituto de Química/UFBA)


A radiação eletromagnética associada ao uso do celular foi classificada como
possivelmente carcinogênica e deve ser alvo de mais estudos, segundo avaliação da agência da Organização Mundial da Saúde (OMS) responsável pelo estudo do câncer (Iarc, na sigla em inglês). A conclusão foi divulgada por 31 cientistas de 14 países reunidos em Lyon, na França, para revisar centenas de pesquisas sobre o risco de uso destes e de outros aparelhos. A evidência foi revisada criticamente e avaliada como limitada entre os usuários de celulares para glioma e neuroma (tumores no cérebro), mas inadequada para conclusões sobre outros tipos de câncer. O grupo de trabalho, diz o texto, não quantificou o risco, mas salientou que uma pesquisa no passado sobre uso de celulares, até o ano de 2004, mostrou um crescimento de 40% no risco de glioma na categoria dos usuários mais frequentes de celular - cerca de 30 minutos por dia ao longo de dez anos. Serão apresentados trabalhos recentes sobre o tema, bem como um testemunho de um episodio ocorrido na França em 2007, referente ao uso de sistemas wi-fi.O objetivo da apresentação é de compartilhar informações visando formar uma opinião crítica sobre o assunto, com base nas últimas informações tornadas públicas, permitindo uma reflexão sobre este possível problema da vida moderna, mais um que evidencia nosso contraditório desenvolvimento.
