7.1 Scenario A: Equipment Fails to Shut Off ("Beam Stuck On")
This section addresses the measurement of radiation levels at the facility.
The most effective RPPs are those that treat radiation not as a mysterious monster, but as a controllable energy. A great RPP does the following:
This section defines the classification of areas within the facility based on radiation levels.
require any organisation handling radiation sources to establish a comprehensive Radiation Protection Plan (RPP)
Dose limits for workers and the public set by the NEA must never be exceeded.
Managing the personal dosimetry program and reviewing monthly dose records.
A full list of all X-ray equipment or radioactive materials (make, model, serial number).
But with great power comes an equally great responsibility—one that the National Environment Agency (NEA) takes very seriously. If you are a Radiation Worker (RW) or a Radiation Safety Officer (RSO) in Singapore, you know that the Radiation Protection Act isn't just red tape; it is the architecture of survival.

| Personnel Type | Minimum Training Requirement | |----------------|------------------------------| | RSO | NEA‑approved RSO course (e.g., from SSG or recognised institution) + refresher every 3 years | | Radiation worker | Basic Radiation Safety Course (e.g., RPA‑certified course) + annual refresher | | Non‑radiation staff (e.g., cleaners) | Awareness training (no formal dose limits, but must not enter controlled areas unescorted) |
Radiation safety fails when responsibility is vague. In Singapore, the structure is distinct.
| Role | Responsibility | | :--- | :--- | | | Provide resources for shielding, PPE, and dosimetry. Enforce disciplinary action for non-compliance. | | Radiation Safety Officer (RSO) | Holds a valid NEA RSO licence. Conducts monthly inventory checks, investigates incidents, reviews monitoring results. | | Radiation Workers | Wear dosimeters, follow Standard Operating Procedures (SOPs), report anomalies immediately. | | General Employees | Stay behind designated barriers. Report broken warning lights. |
