These peculiar beams of radiation were first spotted in the 1960s.

这些奇特的射线波是在1960年首次被发现的。

This creates a neutron star, quirk star or black hole and releases a beam of radiation in the process.

这个过程中会产生中子星、夸克星或者是黑洞并释放出一簇辐射线。

Pinpoint beams of radiation are focused deep inside the brain, and wherever these beams of radiation intersect, they deposit a therapeutic dose of radiation.

精确的辐射光束聚焦在大脑深处，无论这些辐射光束在哪里相交，它们都会沉积治疗剂量的辐射。

This treatment is called stereotactic radiosurgery, and those light beams are beams of radiation: their task is to destroy tumors by gradually scrubbing away malignant cells.

这种治疗称为立体定向放射外科手术，那些光束就是辐射束：它们的任务是通过逐渐清除恶性细胞来摧毁肿瘤。

When several beams of radiation intersect to strike a mass of cancerous cells, their combined force essentially shears the cells' DNA, causing a breakdown in the cells' structure.

当几束辐射相交撞击大量癌细胞时，它们的合力基本上会剪切细胞的 DNA，导致细胞结构崩溃。
