The settlement was founded in 1921 to serve the Peat Experimental Station, which was later transformed into the Institute of Peat Industry. The settlement was known as TOS, an abbreviation from Peat Experimental Station.[9] At the time, it belonged to Klinsky Uyezd of Moscow Governorate.
On July 12 1929, the Governorate was abolished, and TOS was transferred to Moscow Oblast.[10] Uyezds were abolished as well, and Zavidovsky District, with the administrative center in the urban-type settlement of Novozavidovsky, was established within Tver Okrug of Moscow Oblast.[11] Redkino was a part of Zavidovsky District. On July 23, 1930, the okrugs were abolished, and the districts were directly subordinated to the oblast. On January 29, 1935 Kalinin Oblast was established, and Zavidovsky District was transferred to Kalinin Oblast. In 1939, TOS was granted urban-type settlement status. In November and December 1941, during World War II, TOS was occupied by German troops.[9] On November 14, 1960 the district was abolished and merged into Konakovsky District.[10] On February 13, 1963, during the abortive Khrushchyov administrative reform, Konakovsky District was merged into Kalininsky District, but on January 12, 1965 it was re-established.[10]
In 1965, TOS was renamed Radchenko to commemorate Ivan Radchenko, one of the organizers of the peat industry in Russia, who used to live in the settlement.[9] In 1990, Kalinin Oblast was renamed Tver Oblast.
