2) Proactive-Beam Limitation
3) Positive-Beam Lighting
4) Positive-Beam Limitation

Answer 1

PBL stands for Positive-Beam Limitation, a term used in radiation therapy to tailor the radiation beam to the shape of the tumor, protecting surrounding tissues.

Step-by-step explanation:

The abbreviation PBL stands for Positive-Beam Limitation, which is option 4 in the list provided. This term relates to the field of radiation therapy in medicine and refers to a technique used to shape the radiation beam to conform to the shape of the tumor. By using PBL, the radiation can be limited to the tumor area so that surrounding healthy tissues and organs are exposed to minimal radiation. The goal is to maximize the dose to the tumor while minimizing the dose to surrounding normal tissues.
