An electron microbeam system has been installed at the Korea Institute of Radiological and Medical Sciences (KIRAMS) for use in radiation biology studies. The electron beam is produced from a commercial electron gun, and the beam size is defined by a 5 µm diameter pinhole. Beam energy can be varied in the range of 1-100 keV, covering a range of linear energy transfer from 0.4 to 12.1 keV µm-1. The micrometer-sized electron beam selectively irradiates cells cultured in a Mylar-bottomed dish. The positioning of target cells one by one onto the beam exit is automated, as is beam shooting. The electron beam entering the target cells has been calibrated using a Passivated Implanted Planar Silicon (PIPS) detector. This paper describes the KIRAMS microbeam cell irradiation system and its beam characteristics. [ABSTRACT FROM AUTHOR]

The length-weight relationships were analysed for 19 species classified into nine families from the Saemangeum reservoir, South Korea. The sample size ranged from 12 individuals for Silurus asotus and Micropterus salmoides to 548 for Liza haematocheila. Six species have no length-weight information in FishBase.

This study estimated LWRs of fifteen Korean endemic fish species, which had no prior LWR data in fishbase. Fish samples were collected quarterly in the Korean Peninsula from 2010 to 2013 by cast net, gill nets and a kick net. Ranges of parameters a and b of the 15 species were from 0.00398 to 0.01141 and 0.96 to 3.32, respectively. [ABSTRACT FROM AUTHOR]

The length-weight relationships for nineteen freshwater fish species in the Daechung Reservoir, South Korea, were analyzed. LWR data for fourteen of these species were not yet listed in FishBase. [ABSTRACT FROM AUTHOR]

Length-weight relationships of 18 freshwater fish species from the Nakdong River in South Korea are presented. Length-weight relationship data for 10 of these species were not available previously. [ABSTRACT FROM AUTHOR]

The length-weight relationships for eight native freshwater fish species collected in the Geum River, South Korea, were analysed. LWR data for six of the species were not available in FishBase. [ABSTRACT FROM AUTHOR]
