Radiation Protection Quiz

Formula Type

Point Source Rate
Γ × A / d²
Reverse Shielded Activity
A = (Rate × d² / Γ) / transmission
Required Distance
d = √(Γ × A / Ḋ)
Inverse Square Law
Ḋ₂ = Ḋ₁ × (d₁/d₂)²
Combined Sources
Σ (Γᵢ × Aᵢ / dᵢ²)
Unit Conversions
Ci ↔ MBq • µSv/h ↔ mrem/h...
Basic Decay
A = λN • T½ = ln(2)/λ
Time-Based Decay
Aₜ = A₀ × (0.5)^(t/T½)
or
Aₜ = A₀ × e⁻λᵗ
Dead Time Correction
R = Rₒ / (1 - Rₒτ)
Counting Statistics
σ = √N • Confidence Levels
Detector Count Rate
Counts = A × (Area/4πr²) × Eff
Cumulative Dose
Dose = Rate × Time × Occupancy

JSON Import Guide

Basic Structure

Your JSON file must contain a root sections object. Use the Section Title as the key.

{ "sections": { "My Section Title": { "author": "Jane Smith", "questions": [ ... ] } } }

Question Object

You can provide simple lists or advanced randomization.

{ "variants": [ "What is the unit X?", "Select the correct unit X." ], "options": [ ["Sievert", "Sv"], "Gray", "Rem" ], "correct": "Sv", "hint": "Dose equivalent weights absorbed dose by biological impact on human tissue.", "insight": "Gray, Rem, and Sievert are all dose-related units — each used in different systems or for different quantities.", "explanation": "Sievert (Sv) is the SI unit for dose equivalent, replacing the Rem. Gray (Gy) is the SI unit for absorbed dose, replacing the Rad." }

Advanced Sample (Full)

A complete example with 3 questions split across 2 sections.

{ "sections": { "Units & Definitions": { "author": "Dr. A. Becquerel", "questions": [ { "question": "What is the SI unit for Activity?", "options": ["Becquerel", "Gray", "Sievert"], "correct": "Becquerel", "hint": "Activity measures the rate of radioactive decay events occurring per second.", "insight": "Becquerel, Curie, and Gray are all nuclear-related units, each measuring a different physical quantity.", "explanation": "Becquerel (Bq) is the SI unit for activity, equal to one decay per second. The Curie is its older non-SI equivalent." }, { "variants": [ "Select the Dose Equivalent unit.", "Which unit represents Dose Equivalent?" ], "options": [ ["Sievert", "Sv"], "Gray", "Rad" ], "correct": "Sv", "hint": "Dose equivalent weights absorbed dose by biological impact on human tissue.", "insight": "Gray, Rem, and Sievert are all dose-related units, each used in different systems or for different quantities.", "explanation": "Sievert (Sv) is the SI unit for dose equivalent, replacing the Rem. Gray (Gy) is the SI unit for absorbed dose, replacing the Rad." } ] }, "Emergency Procedures": { "author": "Health Physics Dept.", "questions": [ { "question": "What is the first priority in a radiological emergency?", "options": ["Protect People", "Contain Spill", "Notify RSO"], "correct": "Protect People", "hint": "Emergency response follows a hierarchy that places human welfare above all procedural steps.", "insight": "Containing the spill, notifying the RSO, and protecting people are all necessary steps, but their order matters.", "explanation": "Protecting people is always the first priority in a radiological emergency, before containment or notification." } ] } } }

AI party system

Unlocks offline friends slots and party button on the quiz screen, each invidiual friend will remember their solved questions and incorrect choices per question bank, they will acquire exp to level up and become faster and more accurate, they might get exhausted if they spend too much SP and solve questions faster, but with less accuracy.
