The H I line in the vicinity of the radio source W28 has been observed in absorption and emission with the RATAN-600 radio telescope at a resolution of 2.4 arcmin x 45 arcmin x 6.3 km/sec. The absorption line yields a distance of about 3 kpc to the supernova remnant; the compact H II regions observed there are located at the same distance. In emission, an expanding H I envelope 82 pc in diameter has been detected around W28; its mass is 69,000 solar masses and it is expanding at about 20 km/sec. The supernova remnant is 580,000 yr old and the energy of the original explosion was 8.4 x 10 to the 51st erg. Some conclusions are reached as to the possible genetic relation between the H II zones and the SNR.
