This study describes the effect of gamma-irradiation on the microbial skin and organ contamination and on the histological changes of fish skeletal musculature. The aquarium fish Poecilia reticulata were exposed to the radiation effect of 60Co at the doses of 20 and 30 Gy (11.36 Gy/min). Frequent intravital haemorrhages were observed from day 8 after the exposure. A general long-term body fading appeared from day 10 to day 30 of the experiment. Microbiological and histological examinations were done on days 7, 14, 21 and 28. Individual muscle cells were bound together into fascicles surrounded by connective tissue. No significant morphological changes were observed on skeletal muscle cells, except for more watery connective tissue. The presence of Escherichia coli and Aeromonas hydrophila was proved in the body surface samples and in aquarium water based on the microbiological test. A moderate increase of the number of E. coli and A. hydrophila was observed in the intestines in both exposed groups (20 and 30 Gy) depending on the time that elapsed from the exposure (from 1 × 101 to 6 × 103 CFU). However, the heart, liver and musculature remained sterile. No microbial contamination of musculature was found for the intravital ionizing radiation dose of 30 Gy even for the single specimen killed on day 28 from the exposure.

The trend of consuming herbal medicines has been increasing over the past three decades. No less than 80% of the world's population has used herbal medicines as a treatment. One of the problems in herbal medicine is the high level of microbial contamination caused by raw materials and production processes. Various attempts have been made to overcome these problems, one of them is the gamma irradiation method. Although irradiation has been widely used for food sterilization, the use of irradiation for sterilization on herbal medicines is still debated. It is because irradiation may affect the composition of active compounds of herbal medicines. This review aimed to discuss the applications of gamma irradiation for herbal medicines by emphasizing the chemical constituent stabilities of herbal medicines.
