The licensing sequence, the radiation safety officer role, personnel dosimetry, area monitoring and source accounting for a Bangladeshi nuclear medicine department, and the paperwork an inspector opens first.
Nuclear medicine RFQ checklist (TXT)
Plan radiation authorisation and import arrangements alongside the clinical brief, construction and procurement programme. Radioactive consignments have time-dependent usable activity and product expiry, so confirm the necessary permissions and receiving readiness before shipment.
Forms, fees and validity periods are deliberately not quoted below. They change, and the version in a supplier's slide deck is usually three years old. Take those from the regulator directly, at the time you apply.
Distinguish the radiation regulator, isotope and technical service providers, and the medical-device or medicinal-product authority. The relevant permissions depend on the equipment, radiopharmaceuticals and proposed activities; one approval does not replace the others.
BAERA regulates radiation safety and the relevant authorisations in Bangladesh. BAEC operates nuclear and scientific services and may provide isotope, calibration or waste services under agreed arrangements. Confirm applicable DGDA requirements for the device and radiopharmaceutical with the competent authority and importer. Do not describe BAEC as the radiation licensing authority or assume one device approval authorises possession and use of radioactive material.
Two approval chains therefore run in parallel: one for the machine as a traded medical device, one for the radiation. Projects fall over when a team assumes that clearing the first clears the second.
Establish the radionuclides, activity inventory, workload, patient pathways and occupancy with the clinical and physics teams. Obtain qualified layout, structural and shielding assessments and confirm BAERA's required application sequence before construction or import. Arrange shipments only under the relevant permissions and product conditions. Plan authorised commissioning and survey measurements that represent the intended use, followed by documented acceptance and the required operating authorisation. Assign renewal, reporting and source-accounting responsibilities. This is a planning sequence, not a substitute for the current application requirements.
Appoint a suitably qualified radiation protection officer with documented responsibilities, time, management support and escalation authority. Confirm the qualifications and approval required by BAERA. A reporting line supports independence but does not replace competence; combined roles and deputy arrangements must remain workable for the actual workload.
The international occupational framework distinguishes effective dose, lens dose, skin and extremity limits, and the averaging periods that apply to each. A five-year average and a separate single-year ceiling are not interchangeable. Confirm current Bangladesh requirements with BAERA and use qualified advice when establishing local investigation levels and worker monitoring.
Base individual monitoring on the exposure assessment and applicable requirements, including whole-body, extremity or eye monitoring where indicated. Badge position, apron use, control dosimeters, issue periods and investigation follow the dosimetry service and protection programme. An exposed control can bias background correction; it does not necessarily inflate every result. Late return can compromise a record but does not automatically erase the whole monitoring period. Investigate missing or abnormal results and retain documented estimates and records where required.
Dose rate and surface contamination are different quantities and require suitable detector responses, calibration and sensitivity. Some instruments, including configured dual-function designs, provide both functions. Verify each intended measurement rather than asserting that a combined instrument must perform badly.
| Purpose | Instrument | Reads in | Used for |
|---|---|---|---|
| Dose rate | Energy compensated Geiger-Muller or ionisation chamber | Microsievert per hour | Area surveys, package receipt, therapy patient measurement, shielding verification |
| Surface contamination | Thin window pancake Geiger-Muller or scintillation probe, for example the Portable Contamination Monitor LB 124 SCINT Series (LB 124 SCINT, LB 124 SCINT-D) | Counts per second | Benches, floors, hands, exit monitoring, spill clearance |
| Wipe test counting | Well or gamma counter | Activity | Removable contamination against a written action level |
Set calibration, pre-use checks, survey locations and frequencies from the instrument instructions, authorisation and protection programme. Include energy response, measurement range, background, battery condition and trends against a baseline. The programme should cover relevant adjacent occupancy and change after alterations or abnormal events; annual calibration and monthly surveys are not universal requirements for every instrument and task.
Keep contemporaneous source and activity records with a traceable audit trail. Reconcile receipts, transfers, use, waste and remaining inventory with decay and measurement uncertainty considered; a simple subtraction of administered activity from received activity is not sufficient for every radiopharmaceutical process.
Record receipt identification, reference activity and time, required package checks, preparation and QC, administered activity and relevant residuals, transfers and disposal. Apply generator and product-specific QC rather than assuming every assay is required at every elution. Set reconciliation, sealed-source checks and leak-test intervals from the authorised programme. Record source identifiers, certificates and the agreed return route; disused sources remain controlled until authorised transfer or clearance.
| Document | What it has to show | How it usually fails |
|---|---|---|
| Current authorisation and conditions | In date, conditions read and understood | Framed on the wall, never re-read after grant |
| RSO appointment letter | Signed, dated, with explicit authority to suspend work | Verbal appointment, or a name on an organogram |
| Local rules and training records | Written for these isotopes, signed by staff; training with content, date and assessment | A vendor template with another hospital's name still in it, and an attendance sheet with no syllabus |
| Dosimetry records | Continuous by cycle, with the review signed | Gaps in the months when badges went back late |
| Instrument calibration and dose calibrator QC | Traceable certificates in date; constancy, accuracy, linearity and geometry at stated intervals | One certificate from the commissioning year, and linearity never repeated |
| Sealed source register and leak tests | Serial, activity, location, last result | Flood source with no certificate |
| Survey and wipe test records | Mapped points, numbers, and a written action level | Readings with no action level, so nothing is exceeded |
| Incident and near miss log | Entries with corrective actions closed out | Empty, and offered as evidence of safety |
Review incident and near-miss reporting for accessibility, follow-through and learning. An empty log alone proves neither a safe programme nor concealed incidents; examine it alongside training, monitoring, inspection and corrective-action evidence.
Send Vvon the proposed isotope inventory, workload, floor plan and equipment brief to discuss shielding, monitoring and QA products. Qualified institutional teams must establish the protection design and regulatory submissions. Confirm the supplied equipment and specialist work in the quotation.
