H: Occupancy-weighted (mSv/y)

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-46 — Occupancy-weighted) is the form associated with Occupancy-weighted. Working symbols: $Hraw$ , $T$ $\rightarrow$ $H$ . NCRP occupancy. Pedagogical SI sheet with a live model and a swept parameter.

Purpose

Purpose: compute

H

from

Hraw

T

in Radiation protection via

H=H_{raw} T

NCRP occupancy. 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

Hraw = 4.000\,\mathrm{mSv/y}

T = 0.250\,\mathrm{—}

, the governing relation

H=H_{raw} T

yields

H = 1.000\,\mathrm{mSv/y}

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