NRPP RMS study plan

Map the Domain 1 blueprint into a one-page checklist of measurement tasks: device placement, closed-building conditions, deployment and retrieval, chain of custody, and reporting.

Define and recite the core physics vocabulary (radon, radon decay products, half-life, picocurie per liter, working level, equilibrium ratio) without notes.

Distinguish the device families (charcoal canister, alpha-track, electret ion chamber, continuous radon monitor, charcoal liquid scintillation) by deployment duration, sensitivity, and interference risks.

Walk through the closed-building protocol steps and state why each step exists before any device is placed.

Sequence a full measurement event from client call to final report, listing every document generated at each step.

Apply the correct test-duration choice (short-term versus long-term) to five written client scenarios and justify each choice.

Identify quality-assurance components: duplicates, blanks, spikes, cross-checks, and calibration records, and state the acceptance criterion for each.

Interpret a sample result set against the applicable action level and write the client recommendation in plain language.

Diagnose five written measurement errors (device moved, windows opened, HVAC running, device retrieved late, improper placement height) and state the corrective action for each.

Explain the difference between measurement and mitigation professional responsibilities at the handoff point.

Practice the client-communication script for delivering an elevated result, including what not to promise.

Complete a timed 25-question Domain 1 self-quiz and log every missed concept with a one-line correction.

Define soil gas and pressure-field concepts: soil gas concentration, permeability, pressure differential, stack effect, and communication between soil and building.

Explain the driving forces that move soil gas into a building and rank them by typical influence.

Compare sub-slab depressurization, sub-membrane depressurization, and drain-tile/block-wall depressurization by site condition.

Describe the diagnostic steps before system design and what each diagnostic measurement tells the designer.

Lay out the components of an active soil depressurization system and state the function of each: suction point, piping, fan, discharge location, sealing, and system monitor.

Size and route piping for three described buildings, stating the reasoning for diameter, slope, and termination point.

List the sealing and closure details required at penetrations, sumps, and crawlspace membranes.

Explain how the system monitor and a post-mitigation test confirm performance.

Diagnose five written system failures (fan failure, blocked discharge, water in piping, inadequate suction field, backdrafting combustion appliances) and state the fix and the safety check.

Explain combustion-appliance safety testing and when it must be performed relative to system startup.

Describe post-mitigation verification: who tests, when, under what building conditions, and what result counts as success.

Draft the homeowner operating and maintenance instructions for a completed system.

Complete two timed mixed-domain practice sets and tag each miss by domain and by cause (knowledge gap, misread, or guess).

Re-teach the ten weakest concepts from memory in writing, then check against your notes.

Reconcile overlapping standards concepts: which requirements differ between measurement and mitigation work and which are shared.

Build a one-page formula and definition sheet you can reconstruct from memory.

Take two full-length timed practice exams under exam conditions and record section timing.

Review only tagged weak concepts, not full content, in the final days.

Rehearse the reconstruction of the formula and definition sheet from blank paper.

Finalize exam-day logistics: identification, arrival time, calculator policy, and break strategy.
