The Trinity nuclear test was detonated in south-central New Mexico on 16 July 1945; in the early 2000s, the National Cancer Institute undertook a dose and cancer risk projection study of the possible health impacts of the test. In order to conduct a comprehensive dose assessment for the Trinity test, we collected diet and lifestyle data relevant to the populations living in New Mexico around the time of the test. This report describes the methodology developed to capture the data used to calculate radiation exposures and presents dietary and lifestyle data results for the main exposure pathways considered in the dose reconstruction. Individual interviews and focus groups were conducted in 2017 among older adults who had lived in the same New Mexico community during the 1940s or 1950s. Interview questions and guided group discussions focused on specific aspects of diet, water, type of housing, and time spent outdoors for different age groups. Thirteen focus groups and 11 individual interviews were conducted among Hispanic, White, and Native American participants. Extensive written notes and audio recordings aided in the coding of all responses used to derive ranges, prevalence, means, and standard deviations for each exposure variable for various age categories by region and ethnicity. Children aged 11-15 y in 1940s or 1950s from the rural plains had the highest milk intakes (993 mL d), and lowest intakes were among 11- to 15-y-olds in mountainous regions (191 mL d). Lactose intolerance rates were 7-71%, and prevalence was highest among Native Americans. Meat was not commonly consumed in the summer in most communities, and if consumed, it was among those aged 11-15 y of age or older who had relatively small amounts of 100-200 g d. Most drinking and cooking water came from covered wells, and most homes were made of adobe, which provided more protection from external radiation than wooden structures. The use of multiple approaches to trigger memory and collect participant reports on diet and other factors from the distant past seemed effective. These data were summarized, and together with other information, these data have been used to estimate radiation doses for representative persons of all ages in the main ethnic groups residing in New Mexico at the time of the Trinity nuclear test.

用于支持估计来自三位一体核试验的放射性沉降物的辐射剂量的饮食和生活方式的方法和发现。

三位一体核试验于 1945 年 7 月 16 日在新墨西哥州中南部引爆；在 2000 年代初期，美国国家癌症研究所对测试可能对健康产生的影响进行了剂量和癌症风险预测研究。为了对 Trinity 测试进行全面的剂量评估，我们收集了与测试期间居住在新墨西哥州的人群相关的饮食和生活方式数据。本报告描述了为捕获用于计算辐射暴露的数据而开发的方法，并介绍了剂量重建中考虑的主要暴露途径的饮食和生活方式数据结果。2017 年对 1940 年代或 1950 年代居住在同一新墨西哥州社区的老年人进行了个人访谈和焦点小组讨论。访谈问题和指导小组讨论侧重于不同年龄组的饮食、水、住房类型和户外时间的具体方面。在西班牙裔、白人和美洲原住民参与者中进行了 13 个焦点小组和 11 个个人访谈。大量的书面笔记和录音有助于对所有响应进行编码，这些响应用于得出按地区和种族划分的不同年龄类别的每个暴露变量的范围、流行率、平均值和标准差。1940 年代或 1950 年代农村平原地区 11-15 岁儿童的牛奶摄入量最高（993 mL d），而山区 11 至 15 岁儿童的牛奶摄入量最低（191 mL d）。乳糖不耐受率为 7-71%，美洲原住民的患病率最高。大多数社区在夏季不常食用肉类，如果食用，则在 11-15 岁或以上的人群中，其摄入量相对较少，为 100-200 g/d。大多数饮用水和烹饪用水来自有盖的水井，大多数房屋都是用土坯建造的，与木结构相比，土坯提供了更多的外部辐射防护。使用多种方法来触发记忆并收集参与者关于遥远过去的饮食和其他因素的报告似乎是有效的。对这些数据进行了总结，并与其他信息一起，这些数据已被用于估计 Trinity 核试验时居住在新墨西哥州的主要族群中所有年龄段的代表性人员的辐射剂量。大多数房屋都是用土坯建造的，与木结构相比，土坯提供了更多的外部辐射保护。使用多种方法来触发记忆并收集参与者关于遥远过去的饮食和其他因素的报告似乎是有效的。对这些数据进行了总结，并与其他信息一起，这些数据已被用于估计 Trinity 核试验时居住在新墨西哥州的主要族群中所有年龄段的代表性人员的辐射剂量。大多数房屋都是用土坯建造的，与木结构相比，土坯提供了更多的外部辐射保护。使用多种方法来触发记忆并收集参与者关于遥远过去的饮食和其他因素的报告似乎是有效的。对这些数据进行了总结，并与其他信息一起，这些数据已被用于估计 Trinity 核试验时居住在新墨西哥州的主要族群中所有年龄段的代表性人员的辐射剂量。
