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-48 — Skyshine scale) is the form associated with Skyshine scale. Working symbols: $H1$ , $d$ $\rightarrow$ $H$ . Pedagogical 10 m reference. Pedagogical SI sheet with a live model and a swept parameter.

Purpose

Purpose: compute

H

from

H1

d

in Radiation protection via

H\\propto 1/d^2

Pedagogical 10 m reference. 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

H1 = 80.000\,\mathrm{nSv/h}

d = 30.000\,\mathrm{m}

, the governing relation

H\\propto 1/d^2

yields

H = 8.889\,\mathrm{nSv/h}

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