KUALITAS UDARA Dalam RUANGAN – RADON dan ASBES

Radon adalah Gas yang tidak berwarna dan tidak berbau , menjadi  penyebab kanker paru-paru di USA, menewaskan sekitar 21.000 orang setiap tahun .

Hampir semua tanah mengandung sedikit uranium yang sedang melapuk, yang memancarkan radon , meskipun daerah-daerah tertentu konsentrasimnya lebih tinggi dari daerah lainnya.  Biasanya gas ini  menghilang ke udara luar , tetapi juga dapat mengalir ke dalam bangunan melalui celah-celah di lantai , dan akhirnya mencapai konsnetrasi yang tidak aman di dalam ruangan .

Rata-rata konsentrasi radon dalam ruangan (di USA) adalah 1,3 curie pico per liter ( pCi / L ) , dan EPA merekomendasikan mengambil tindakan jika terdeteksi konsentrasi gas Radon  4 pCi / L atau lebih tinggi .

Remediasi Radon melibatkan isolasi interior bangunan dari tanah yang tercemar.

 

Asbes

Asbes terdapat secara alami dalam tanah , risiko kesehatan nya relatif kecil kalau ia tidak masuk ke dalam ruangan. Serat mineral tahan panas telah lama digunakan sebagai bahan bangunan dan isolator, tetapi banyak laporan bahwa menghirup serat asbes dapat menyebabkan kanker paru-paru , mesothelioma dan gangguan jaringan parut pada paru-paru .

Rumah dan kantor modern sekarang telah menggunakan bahan alternatif , tetapi bangunan tua mungkin masih mengandung banyak asbes . Bahan alternatif ini hanya menghasilkan  serat halus di udara kalau telah mengalami kerusakan, sehingga solusi yang paling praktis adalah meninggalkan (tidak menggunakan) bahan asbes .

Jika dicurigai suatu bahan yang mengandung asbes , perhatikan tanda-tanda kerusakan
