The first-principal calculations of thermodynamical and structural properties of barium and radium under moderate pressures are carried out. The possibility of the occurrence of structural phase transitions f.c.c.–b.c.c. and b.c.c.–h.c.p. in them is examined. Results of calculations indicate a big similarity of thermodynamic properties and characteristics of structural phase transitions in barium and radium.

Key words: alkaline-earth metals, structural phase transition, band structure calculations.
