health physics

health physics的音标是[ˈhelθ ˈfɪzɪks]，基本翻译是“健康物理学”，速记技巧是“健康物理”记发音。

Health physics 是一个专业领域，涉及健康和物理学的交叉学科。这个词的词源可以追溯到拉丁语和希腊语，具体如下：

Health (health)来自拉丁语的“sanitas”，意为“健康，健全”。Physics (physics)来自希腊语的“φυσική”，意为“自然，物理学”。

相关单词及其变化形式：

1. radiation - 来自拉丁语的“radium”，意为“光线，辐射”。其复数形式“radiations”可以表示放射性物质或放射性辐射。

2. radiation dose - 辐射剂量，dose是重量或剂量的意思，这里表示辐射的量。

3. radiation protection - 辐射防护，protect是保护的意思。这个词表示保护人们免受辐射伤害。

4. radioactivity - 放射性，radio-是放射性的前缀，activity表示活动。这个词表示具有放射性的物质。

5. radiotherapy - 放射治疗，therapy是治疗的意思，radiotherapy结合了放射和治疗的含义。这个词用于治疗癌症等疾病。

6. neutron - 中子，由希腊词根“neos”和“tronos”组成，分别表示新和长。这个词表示一种不带电荷的粒子。

7. neutron radiation - 中子辐射，是中性粒子的辐射形式。

8. biophysics - 生物物理学，bio-表示生命，physics表示物理学，所以biophysics就是研究生命与物理学的交叉学科。

9. health physics - 健康物理学，这个单词是由health（健康）和physics（物理学）组成的，专门研究如何减少辐射和其他物理因素对健康的负面影响。

10. physical agent - 物理剂，agent是代理或工具的意思，这个词表示物理因素或物理粒子，如放射性物质或中子等。

以上就是health physics的英文词源、变化形式以及相关单词的解释和描述，希望对你有所帮助。
