The 2011 earthquake severely damaged the Fukushima Daiichi Nuclear Power Plant (FNPP), resulting in the release of large quantities of radioactive material into the environment. The deposition of these radionuclides in rice straw as livestock feed led to the circulation of contaminated beef in the market. Based on the safety concern of the consumers, a reliable method for estimating concentrations of radioactive cesium in muscle tissue is needed. In this study, we analyzed the concentrations of radioactive cesium in the blood and skeletal muscle of 88 cattle, and detected a linear correlation between them. We then developed software that can be used to estimate radioactive cesium concentrations in muscle tissue from blood samples. Distribution of this software to the livestock production field would allow us to easily identify high-risk cattle, which would be beyond the safety regulation, before shipping out to the market. This software is planned to be released as freeware. This software would contribute to food safety, and aid the recovery of the livestock industry from the damage creacted by the 2011 Tohoku earthquake and tsunami.
2011年的地震严重破坏了福岛第一核电站（FNPP），导致大量放射性物质释放到环境中。这些放射性核素沉积在稻草（作为牲畜饲料）中，致使受污染的牛肉在市场上流通。基于消费者的安全担忧，需要一种可靠的方法来估算肌肉组织中放射性铯的浓度。在本研究中，我们分析了88头牛的血液和骨骼肌中放射性铯的浓度，并检测到它们之间存在线性相关性。然后，我们开发了一款软件，可用于根据血液样本估算肌肉组织中的放射性铯浓度。将该软件推广到畜牧生产领域，将使我们能够在牛只运往市场之前轻松识别出超出安全规定的高风险牛只。该软件计划作为免费软件发布。此软件将有助于食品安全，并助力畜牧业从2011年东北地震和海啸造成的损害中恢复过来。
