Lecture brief

Historical brief

Inverse-square, half-value layer, ICRP weighting and ALARA are the protection craft since the 1920s commissions. The lab computes transmission, equivalent dose and a shielding snapshot. This sheet (RPR-47 — Workload W) is the form associated with Workload W. Working symbols: $N$ , $mAmin$ $\rightarrow$ $W$ . X-ray room workload. Pedagogical SI sheet with a live model and a swept parameter.

Purpose

Purpose: compute

W

from

N

mAmin

in Radiation protection via

W=N\\, mA\\, min

X-ray room workload. Use it when a real radiation protection question must be answered in SI before a code check.

Live realistic example

In symbols

Live case. Given

N = 40.000\,\mathrm{1/wk}

mAmin = 20.000\,\mathrm{mA·min}

, the governing relation

W=N\\, mA\\, min

yields

W = 800.000\,\mathrm{mA·min/wk}

. One governing identity, SI units, a single sweep on the sheet. Move a slider: the numbers are this situation, not a canned story.
