New amendment added #2: The RFQ has been further amended in order to:1) extend the quotation submission deadline from 04-June-2026 till 11-June-2026:2) replace the document titled "RFQ_2026_62758_Section III_Returnable Bidding Forms_Form C_Technical Bid Form" with the document titled "RFQ_2026_62758_Section III_Returnable Bidding Forms_Form C_Technical Bid Form_REV1_03JUN2026" that introduces amendments (in red font) made to several technical requirement lines in Lots #1 and #2. 

New clarification added: Q7:Reference is made to technical requirement line # 26 k. "Minimum pulse duration of pulsed X-ray radiation: 1 ms." of Lot #1: Automated system with gamma and X-ray dosimeters.  Typically pulse durations in medical fields are longer than 2 ms. The versions of dosimeters with special Industrial X-Ray mode are able to count doses with down to 1 µs pulses, but they are more expensive, due to big number of purchased dosimeters – 1000 pcs, this would result in significant increase of the total price. While most likely only a few dosimeters out of 1000 will be used for such very specific tasks. These very specific tasks typically can be found in work fields like linear accelerators (LINACs), pulsed neutron/gamma facilities, or other specialized physics experiments. And for such rare cases, it's much better to use specialized dosimeters that should properly count doses with much shorter than 1 ms, down to 1 µs. It would be more reasonable, considering the cost of all dosimeters, to purchase only a subset of the ultra-short pulse dosimeters for such specialized work, for example 50 units, and the rest 950 would be standard versions suitable for routine work, where pulses are not shorter than 2 ms. Considering everything above would one of the following be acceptable: a) all 1000 dosimeters will be able to count doses with pulsed radiation with duration down to 2 ms or b) 950 dosimeters with pulsed radiation with duration down to 2 ms and 50 dosimeters with count doses with pulses down to 1 µs.  A7: Proposed changes accepted.The requirement for the whole quantity will be changed to "k. Minimum pulse duration of pulsed X-ray radiation: 2 ms."

New clarification added: Q6:Reference is made to technical requirement line # 12. "Built-in battery, Use of replaceable batteries (AAA 1.5 V) is acceptable." of Lot #1: Automated system with gamma and X-ray dosimeters. Could you please clarify, if  AA replaceable battery would be also acceptable? It is practically same size/availability and capacity batteries. A6:Proposed changes accepted. Requirement will be changed to "Built-in battery, Use of replaceable batteries (AAA 1.5 V or AA 1.5 V) are acceptable". An updated document "RFQ_2026_62758_Section III_Returnable Bidding Forms_Form C_Technical Bid Form" will be uploaded in the Documents section of the RFQ.

New clarification added: Q5:Reference is made to technical requirement line # 28. m. "Memory at least  3000 events" of Lot #1: Automated system with gamma and X-ray dosimeters. A5: Would it be considered to reduce requirement to at least 2000 events. This is more than enough for most tasks, and many other reliable manufacturers have such or lower memory capacity, just because more is not needed. Even 1500 is more than sufficient for all possible reasonable use scenarios. The dosimeter's history can be read when it is returned to the issuer, and typically it is no less frequently than when it need to be returned for battery change or recharge. Typically, battery life is not more than two months in continuous run. In such a severe scenario, the dosimeter can store the dose every hour of operation, and this will only require 1440 data cells. In reality, such dosimeters are issued for a shorter period, and 1500 events memory are more than enough for all possible scenarios.  A5:Proposed changes accepted. Memory parameter will be changet to "at least  1500 events". An updated document "RFQ_2026_62758_Section III_Returnable Bidding Forms_Form C_Technical Bid Form" will be uploaded in the Documents section of the RFQ. 

New clarification added: Q4:Reference is made to technical requirement line # 15. b. "Sensitivity range to beta at least: 220 keV – 2.3 MeV" of Lot #1: Automated system with gamma and X-ray dosimeters. Would it be acceptable to offer dosimeters with declared energy region for beta from 220 keV to 1.5 MeV. Most beta radionuclides have maximum beta energy up to 1500 keV. Also, beta spectra are not discreet, but it emits beta particles with energy from 0 to E-max (endpoint). Mean beta energy (Eβ(mean)) is always less than max. so, for most real cases and radionuclides/scenarios, declared energy region from 220 to 1500 keV is fully sufficient and ensures proper dose calculations if dosimeter is compliant with standard IEC 61526.  A4: Proposed changes accepted. Sensitivity range to beta will be changed to "at least: 220 keV – 1.5 MeV". An updated document "RFQ_2026_62758_Section III_Returnable Bidding Forms_Form C_Technical Bid Form" will be uploaded in the Documents section of the RFQ.

New clarification added: Q3: Reference is made to technical requirement line # 14. a. "Sensitivity range to photon (x-ray and gamma) at least: 15 keV – 10 MeV" of Lot #1: Automated system with gamma and X-ray dosimeters.There is an international standard for such type of instruments - IEC 61526: Radiation protection instrumentation - Measurement of personal dose equivalents for X, gamma, neutron and beta radiations - Active personal dosemeters. EPDs are compliant with this standard requirements, however, not compliant with Tender requirements. Would it be acceptable, if declared energy region will be from 16 keV? The difference between these values (15 and 16 keV, it is like 15 and 16 mm when talking about device with 10 meters length) ​​is more formal than meaningful; some manufacturers test and specify one selected set of values ​​in their specifications, while others specify different values. The main thing is that the dosimeter meets the IEC 61526 standard's requirements.  A3:Proposed changes accepted. Sensitivity range to photon (x-ray and gamma) will be changed to "at least: 16 keV – 10 MeV". An updated document "RFQ_2026_62758_Section III_Returnable Bidding Forms_Form C_Technical Bid Form" will be uploaded in the Documents section of the RFQ.

New clarification added: Q2:Reference is made to technical requirement line #13 Strips: of Lot #1: Automated system with gamma and X-ray dosimeters. Is it understood correctly that the strips refer to detectors? A2:Yes, it is correct, strips refer to detectors. 

New amendment added #1: The RFQ has been amended in order to extend quotation submission deadline from 21-May-2026 till 04-June-2026.

New clarification added: Q1a: According to Section III, Returnable Bidding Forms, Form C: Technical Bid Form, Lot #2, S/N 5b specifies: “at least 10.000 TLD Cards compatible with the reader”. Please clarify the term “TLD Cards”. Is it an integral, solid item with the thermoluminescence elements in it and cannot be dismantled.A1a: The item refers to a high-volume, PC-based TLD badge reader system. TLD (Thermoluminescent Dosimeter) cards are passive radiation badges used to measure a worker's accumulated dose from ionizing radiation (specifically X-ray, gamma, and high-energy beta). They consist of a plastic or aluminum card containing 2 to 4 small, disc-shaped crystals (often Lithium Fluoride or Li-Mg,Cu,P) that act as the detectors. When radiation passes through the crystal, it excites electrons and traps them in higher-energy states. The cards are collected periodically and placed in a TLD reader, which heats the crystals to approximately 250°C. This causes the trapped electrons to return to their ground state and release energy as light, the output of which is proportional to the absorbed radiation dose.Q1b: According to Section III, Returnable Bidding Forms, Form C: Technical Bid Form, Lot #2, S/N 6c specifies: “at least 10.000 TLD Badges compatible with the reader”. Please clarify the term “TLD Badges”. Please clarify the statement “compatible with the reader”. How can the badges interfere with the reader?A1b: TLD cards are passive radiation badges. Please refer to the explanation provided in A1a.Q1c: According to Section III, Returnable Bidding Forms, Form C: Technical Bid Form, Lot #2, S/N 17j specifies: “Automatic element-sensitivity correction, background subtraction and pre- and post-calibration capability”. The mentioned above operations in automatic regime are possible if the reader is equipped with an internal irradiator. Please confirm the reader must be equipped with an internal irradiator.A1c: The system does not strictly require an internal irradiator to perform automatic element-sensitivity correction, background subtraction, or pre- and post-calibration. Advanced software-based algorithms and alternative calibration strategies can achieve the same results. It is the bidder's responsibility to offer an adequate solution that performs all required functionalities.Q1d: According to Section III, Returnable Bidding Forms, Form C: Technical Bid Form, Lot #2, S/N 30d specifies: “TLD Card Material: LiF:Mg,Ti Card”. Please clarify the term “TLD Card Material”. Is LiF:Mg,Ti the material of the thermoelements or of the cards. What the Cards are made of?A1d: Please refer to the explanation provided in A1a.
