 erm oscillations with periods of a few tens of minutes obtained from Nobey
 ama radioheliograph (NoRH) at frequency 17 GHz. In number of active region
 s the fluctuations of  radio emission of different types of sources (spots
 \, compact and extended intersunspot sources (ISS)) were compared with the
  fluctuations in magnetic fields of sunspots. More significant correlation
  between the variations in magnetic field and radio emission was observed 
 for sunspots and compact ISS.\nWe adopt the cross-correlation analysis\, w
 avelet analysis\, and statistical tests to deduce the results. The model o
 f the shallow sunspot’s eigen oscillations is discussed  for explanation
  of the origin of quasi-periodic oscillations in sunspots and ISS.\n\nhttp
