Abstract
The broad-band 0.1-200 keV spcctra of a selected sample of Seyfert 2 g alaxies have been measured within the BeppoSAX Core Programme. Here we present the first results obtained for 3 objects, NGC 7172, MKN 3 and NGC 7674. The broad band BeppoSAX data illustrate the high spectral c omplexity often found in Seyfert 2 galaxies predicted by unified model s: NGC 7172 is found to be a Compton-thin source in which the primary emission is seen through absorbing material; MKN 3 is a border line ob ject where the emission is partly seen directly and partly reprocessed by the absorbing material; NGC 7674 is an example of a Compton-thick source where the primary emission is hidden and only reprocessed radia tion is observed.
