Final answer:
The operator radiation near scattered radiation is directly proportional to the patient radiation dose. This relationship depends on the RBE as well as the type of radiation and the impacted tissue.
Step-by-step explanation:
The operator radiation close to scattered radiation is directly proportional to the patient radiation dose. This means that as the scattered radiation near the operator increases, the radiation dose to the patient also increases at a constant ratio. When discussing the effects of ionizing radiation on biological tissue, the dose in rads and the relative biological effectiveness (RBE) are crucial considerations. The number of ion pairs and the resultant damage are directly proportional to the amount of ionizing energy deposited, and the concentrated damage is harder for the organism to repair. Therefore, the biological effects, and hence the patient radiation dose, are affected not only by the amount of radiation but also by its type and the tissue it impacts.
