Janis Guntis BERZINS
Born: January 31, 1936, Riga, Latvia
Interests:
- Nuclear Structure
- Nuclear Reactions
- Radioecology
- Application of the Methods of Nuclear Spectroscopy for Environmental Control
Brief description of main research:
I am working in the area of experimental nuclear spectroscopy. My main scientific
interests are devoted to the investigation of nuclear structure in nuclear reactions in
the mass region A=140-194. I has participated in developing of the experimental equipment
for the nuclear structure investigation in the nuclear reactions at the Latvian nuclear
reactor as well as in investigation of more than 20 nuclei in co-operation with many
laboratories in Europe and USA. Since 1986 we are
active in the field of application of some nuclear spectroscopic methods to ecological
problems. During the last years our laboratory have performed measurements for the
determination of radionuclide concentration in aerosols, precipitation, water and
sediments in Latvia.
