Backscatter becomes negligible at what voltage as the majority is directed in a forward direction (seen in Radiation Therapy range)?

 A 72 year old man was brought on a stretcher to the department for a chest series. The department’s routine includes a frontal and left lateral projection. The patient is suffering from shortness of breath (SOB) and unable to stand erect for the examination. Images of the chest are routinely performed using a 72″ SID. This distance requires a technique of 10 mAs and 100 kVp. Since the patient cannot stand, the exam must be performed using only a 36″ SID. The mAs which should be employed for this SID is

After this exam, it is completely acceptable to celebrate, sleep for 12+ hours, and avoid all radiology-related thoughts for at least 24 hours.
