Thomas Borak designs radioactivity alarm for astronauts and everyone

EarthSky

Thomas Borak: Radiation can provide injury to humans. At rather low doses of radiation, there’s the possibility that an individual could develop cancer.

汤姆斯·博拉克: 辐射会对人体造成伤害。低剂量的辐射也可能诱发个人癌症。

You are listening to radiation physicist Thomas Borak at Colorado State University. With support from the National Space Biomedical Research Institute, Dr. Borak is developing a device to monitor and warn astronauts of radiation in space during extended missions.

你正听到的是科罗拉多大学放射物理学家汤姆斯·博拉克的发言。在美国国家航天生物医学研究中心的帮助下，博拉克博士正在研发一种装置，用于监控宇航员在执行外太空任务所接收的辐射强度，并给其警告。

Thomas Borak: There is concern that they would develop a cancer if they’re exposed while they’re outside of their space vehicle to a solar particle event. This could be a very, very serious situation.

汤姆斯·博拉克：如果宇航员出太空舱活动暴露在大阳粒子辐射下，他们很可能会患上癌症。这可能是一种非常危急的处境。

Dr. Borak said that this dosimeter monitors doses of radiation a person receives, and transmits up-to-the-minute information to a computer. Cancer patients here on Earth who undergo new forms of radiation therapy using protons or carbon ions, said Borak, could also benefit from the dosimeter.

博拉克博士说这种放射量测定器监控人体接收的辐射剂量，将信息即时传给计算机。他还说在地球上正接收质子或碳离子新辐射疗法治疗的癌症患者也会从该放射量测定器收益。

Thomas Borak: When you’re delivering radiation to a cancer patient, you’re trying to deliver an extremely high dose to the tumor. But you want to make sure there are not other locations on the patient at that might receive a dose.

汤姆斯·博拉克：当通过辐射治疗癌症患者时，你尽量为肿瘤施以高剂量的辐射。但是你还需保证病人其他部位免受辐射。

Borak added that the dosimeter is in the testing phase and hopes it will provide valuable improvements to radiation dosimetry in the coming years.

博拉克补充说放射量测定器还处在测试阶段，他希望未来几年该设备能更好的完善辐射剂量测定方法。

Our thanks to the National Space Biomedical Research Institute – innovations for health in space and on Earth.

我们要感谢美国国家航天生物医学研究中心——为人类在太空和地球的健康而不断创新。
