A nuclear accident (e.g., Fukushima), and, in particular, the transport of animals within a radiation-affected area can lead to a whole-body, or partial external irradiation, followed by oxidative stress, which could result in subsequent meat quality changes. In this experiment, live pigs were exposed to half-body irradiation by an external dose of 1.0 Gy. The caudal half of the animal's body was irradiated. After their slaughter, samples from the muscle tissue of and at the upper margin of (irradiated body half) and at the 3-4 thoracic vertebra (non-irradiated half) were collected to determine the meat quality parameters. A significant difference ( < 0.05) was observed only in the meat colour parameter (a*) in the irradiated group of pigs. If there is no internal contamination, and the half-body exposure to the external radiation dose does not exceed 1 Gy, pigs from an irradiation-affected area may be used for human consumption.
核事故（如福岛核事故），特别是受辐射影响地区内动物的运输，可能导致全身或部分身体受到外部照射，继而引发氧化应激，这可能导致随后的肉质变化。在本实验中，对活猪进行了1.0 Gy的外照射半身照射。照射动物身体的后半部分。屠宰后，从照射身体半部上边缘和第3 - 4胸椎（未照射半部）处采集肌肉组织样本，以测定肉质参数。仅在受照射猪组的肉色参数（a*）中观察到显著差异（P < 0.05）。如果没有内部污染，且半身接受的外部辐射剂量不超过1 Gy，受辐射影响地区的猪可用于人类食用。
