In 1976, Marynovych met
Mykola Matusevych, and became a founding member of the
Ukrainian Helsinki Group. Since then he was repeatedly detained by police in
Kyiv and
Serpukhov. Searches were conducted in
Drohobych, and he was constantly threatened. Eventually, because of their membership, Marynovych and Matusevych were arrested on 23 April 1977, on the charge of "
Anti-Soviet agitation and propaganda". There he took part in all human rights actions, held
hunger strikes, including a 20-day protest, and narrated a camp chronicle. For the whole term he had about 150 days of
solitary confinement in a ShIZO cell (ШИЗО, from Штрафной ИЗОлятор/Shtrafioi Izolyator). In 1978,
Amnesty International identified Marynovych as a
prisoner of conscience. After completing his seven years imprisonment in April 1984, Marynovych was exiled to the village of
Saralzhin in the
Oiyl District of
Aktobe region of
Kazakhstan, where he worked as a
carpenter. He married Lyuba Kheina, who travelled from Kyiv to join him in exile. == Later activities ==
