Consideration has been given to the process of decomposition 
of a gas hydrate saturating a porous volume under the action of the 
energy of radiation through its boundary. It has been adopted that 
the zone lying in the vicinity of the boundary and saturated with 
the products of decomposition of the gas hydrate is transparent to 
radiation; the far zone saturated with gas hydrate and gas, conversely, 
is completely opaque; therefore, the radiation energy is totally absorbed 
at the boundary of phase transitions between the zones mentioned. 
The self-similar solutions of plane one-dimensional and radial-symmetric 
problems have been constructed. The influence of the radiation intensity 
and of the parameters of the porous medium-solid gas hydrate-gas 
system in the initial state on the maximum pressures produced in the 
zone of decomposition of the gas hydrate has been analyzed based on 
the analytical solutions obtained.
