Applied science: radiation, ventilation, heat and force
CSP video lesson, 7:15. CSP Domain 6: Occupational Health and Applied Science
Narrated with an AI-generated voice. The script is AI-drafted from the cited rules and fact-checked against them.
Worked CSP exam calculations: radioactive decay, inverse square, half-value layers, dilution ventilation, WBGT and force, each tied to its primary-source formula.
Included with every CSP pass, with captions, chapters and the full transcript. Every rule and number is cited on screen to its primary source.
What this lesson covers
In this lesson, you'll learn to: apply radioactive decay and the inverse square law, use half-value layers to size shielding, size dilution ventilation and compute WBGT, and apply force equals mass times acceleration. Two equations drive most radiation questions. Activity falls with time, and intensity falls with distance. Decay: activity after time t equals A-naught times e to the minus lambda t.
