First level nuclear medicine workplaceprotective equipment(Usually refers to carrying outThe core principle of the protective equipment configuration for departments that do not carry out large-scale iodine-131A cancer treatment, such as SPECT imaging and partial bone metastasis treatment, is“Meet diagnostic and basic treatment needs, implement zoning management, and ensure the safety of staff, patients, and the public”.

According to Chinese standardsrequirementThe following is a list of key protective equipment required for Level 1 nuclear medicine construction, classified by functional areas and processes,

1 Radioactive drug operation and packaging area (high activity room)/Packaging Room

This is the core area of protection, where all open source operations are carried out.

1. Ventilation hood: Core equipment.

²requirementsUsed for the packaging and dilution of all radioactive drugs. There must be sufficient ventilation speed (face wind speed)≥0.5m/s）， The exhaust port needs to be equipped with an efficient filtering device (for possible aerosols),If operating iodine-131, a dedicated activated carbon filter must be equipped.

²Type:According to the operational nuclide, configureiodine-131 Special Ventilation Cabinet(with lead shielding and activated carbon filtration) or universal fume hood.

2. Radioactivity meter: Core equipment.

²Function:Used for measuring and calibrating the activity of radiopharmaceuticals, it is the dosage givenThe eyes. Regular calibration is required.

3. Drug packaging shielding device:

Manual packaging:Syringe protective cover、Syringe protective boxThis is the most basic protective configuration.

·Optional upgrade:For packaging with certain activity (such as strontium for bone therapy)-89, etc.), can be equipped with semi-automatic packaging equipment or simple glove box packaging boxes to enhance protection.

4. Surface pollution and radiation monitoring equipment:

²Surface contamination meter:Used to check whether there is radioactive contamination on the workbench, equipment, and hands. Must be equipped.

²portableX/γ dose rate meter:Used to measure the radiation level around the workplace. Must be equipped.

²Regional radiation monitoring and alarm system: used to continuously monitor and alarm the radiation level in the control area (packaging room, medication room, ward). It is not mandatory to install, but it is strongly recommended to configure and is becoming a standard configuration in the construction of modern nuclear medicine disciplines

5. Drug delivery system:

²Shielded transmission window:Used to safely deliver packaged drugs to injection rooms or wards, avoiding personnel carrying them directly through other areas.Highly recommended.

²Mobile injection protection vehicle:For the protection of special patients during flexible injection at any time.

II Patient administration and waiting area

1. Injection protective screen:Must be equipped.

·Nurses use lead glass or lead acrylic protective screens to protect the thyroid and torso of patients when injecting radioactive drugs.

2. Syringe shielding cover/transport tank:

·Place the syringe containing the extracted medication into a small containerProtective boxTransport from the packaging room to the injection site.

3. Dedicated waiting room/ward:

·Shielding design: Walls, doors and windows should have appropriate lead equivalent shielding (calculated based on the activity of the nuclide used).

·Special toilet: It must be equipped with a radioactive wastewater decay pool or a dedicated collection tank. This is a mandatory requirement for environmental impact assessment.

·Internal facilities: Beds, chairs, etc. should be easy to clean. Provide dedicated covered trash cans for collecting radioactive solid waste.

III Imaging and Diagnostic Area（SPECT/CT 室）

1. Inherent shielding of equipment:The design of the SPECT/CT machine room itself needs to comply with radiation protection standards (sufficiently thick concrete walls or added lead plates).

2. Protection for medical staff:

·Mobile lead screen:Used when positioning or in contact with patients who have just taken medication.

·Personal protective equipment:Although less used in this area, it needs to be equipped.

4 General and Supporting Devices

1. Personal protective equipment (PPE): All employeesNeed to be equipped.

·Lead clothing/lead apron(Commonly used)0.35mm or 0.5mm lead equivalent)

·Thyroid lead scarf

·Lead protective goggles

· Disposable protective clothing, gloves, shoe covers

2. Radioactive waste management system:

·Radioactive solid waste bin:Collect by classification with shielding (lead drum) and radioactive labeling.

· Radioactive waste collector:Used to collect and visualize patient excreta, rinse water, etc.

· Decay storage box/Storage room:Used for centralized storage of solids until they decay to a clean and uncontrollable level.Must be equipped.

3. Personal dose monitoring:

· Personal dosimeter:Equip each staff member with regular inspections. Mandatory regulatory requirements.

·Optional: Can be equipped withPersonal dose alarm deviceUsed for real-time alarm when entering high activity areas.

4. Emergency cleaning supplies：

·Special cleaning agents, absorbent paper, plastic bags, etc.

Core recommendation:

1. Provide "basic package" and "upgrade package":

· Basic compliance package:Targeting first level departments with limited budgets, including all of the above-mentioned“required”Equipment, ensure acceptance.

· Security upgrade package:increaseDrug delivery window, semi-automatic packaging equipment, better personal protectionWait, improve work experience and safety.

·Future Expansion Reserve:When designing fume hoods, ducts, and room shielding, it is recommended that customers consider possible future scenariosLevel 2Upgrade (carry out cancer treatment) reserved interfaces or spaces.

2. Emphasize process oriented solutions:

·PressDrug reception → storage → packaging → delivery → injection → patient management → waste disposalThe entire process of designing and selecting supporting equipment for customers. This can demonstrate your professionalism.

3. Focus on“Level 1”Compared to 'Level 2/Level 3'”The difference:

·canto make clear:First level departments usually do not require or should not be configured for high-dose iodine-The fully automatic packaging machine for 131 treatment, patient specific protective ward (with thick shielding), and super thick fume hood.canReasonably plan the budget and avoid overinvestment.

total knot：

The core of the protective equipment configuration for first level nuclear medicine construction is“Clear zoning, solid foundation, and compliant processes”. Starting from meeting the mandatory requirements of regulations, build a safe, efficient, and resilient protection system. This list is for you as a customerbuildThe basic blueprint for the 'turnkey' project.
