About this file
This document contains the detailed specifications and requirements for the Spectroscopic Pagers (aka Rad Pagers) that the Massachusetts Army National Guard (MAARNG) 1st Weapons of Mass Destruction Civil Support Team (WMD-CST) is seeking to procure. The requirements cover key features such as display, measurement range, alarms, size, data communication, radionuclide identification, and operating conditions. The related federal contract opportunity, Solicitation Number W912SV-24-Q-0018, seeks to acquire 9 of these spectroscopic pagers for use by the MAARNG J-HAT team. The solicitation is a combined synopsis/solicitation for commercial services, with award based on price only. Responses must be submitted electronically, and questions must be received 5 business days prior to the response due date. Delivery of the pagers is required within 60 days of contract award.

Spectroscopic Pagers (aka Rad Pager)
The below specifications will meet the intent and needs for the 1st WMD-CST IAW the Common Table of Allowances (CTA) 50-909, Table 81.
Display
The instrument shall directly display the measured exposure rate or dose-equivalent rate with the associated radiological unit (e.g., μR/h, μGy/h, or μSv/h).
Effective range of measurement
The effective range of measurement shall be at least 5 μR/h to 2 mR/h(0.05 μGy/h to 20 μGy/h).
Audible alarms
The instrument shall provide an audible alarm to indicate an increase in the radiation level that is greater than the alarm set point. The frequency of an audible alarm signal shall be from1000 Hz to at least 4000 Hz. Where an intermittent alarm signal is provided, the interval shall not exceed 2 s.
The A-weighted alarm signal volume at a distance of 30 cm from the instrument shall be at least 80 dB(A) and shall not exceed 100 dB(A).
Vibration alarm
The instrument shall have a vibration alarm signal capability. The vibration alarm shall have sufficient intensity to inform the user of an alarm condition. The intensity of the vibration at the surface of the instrument shall be greater than
0.8 g. The vibration motor used by the instrument should rotate between 9 000 rpm and11 000 rpm.
Size
The overall dimensions of the instrument should be (within the rectangular solid defined by 20 cm in length, 10 cm in width, and 5 cm in depth).
Data format and communication interface
The instrument shall have the ability to transfer data to an external device, such as a computer. The transfer should be based on a bi-directional port that meets the requirements of Ethernet, USB, wireless, or other electronic means, such as a removable media device.
Spectral identification
a) The instrument shall have the ability to store and transfer at least fifty complete (unprocessed) spectra. Each stored spectrum shall contain collection and identification results information in the ANSI N42.42 format including:
• Time and date
• Instrument type and serial number
• Hardware and software version
• Identified radionuclides and associated confidence indications
• Spectrum collection time interval
• Measured gamma-ray exposure rate
• Neutron count rate at the time of measurement, if provided
b) An indication shall be displayed (e.g., “not identified,” “unknown radionuclide”) if a radionuclide cannot be identified.
c) The instrument shall indicate if the exposure rate is too high for radionuclide identification. The false alarm rate for gamma and neutron (when applicable) shall be less than or equal to one alarm activation in a 10 h period when operated in a stable background environment.
Time-to-alarm; photons
The alarm shall activate within 2 s after exposure to an increase in the ambient radiation level of 50 μR/h (0.5 μGy/h) that occurs over a period of not more than 0.5 s.
Time-to-alarm; neutrons
The neutron alarm shall activate within 5 s after exposure to an un-moderated neutron field that occurs over a period of not more than 2 s.
Accuracy
Displayed exposure rates shall be within ±30% of the conventionally true value of the applied exposure rate using 241Am, 137Cs, and 60Co.
Over-range response
When exposed to a radiation field that is two times the maximum exposure rate specified by the manufacturer, the indication of the instrument shall remain at the maximum of that range and an over-range indication shall be displayed for the duration of the exposure. The instrument shall respond normally(recover) within a time period of 5 min after the exposure is reduced.
Radionuclide identification
• Special nuclear materials (SNM): Uranium (used to indicate 233U, 235U, 238U), 237Np, 239Pu
• Medical radionuclides: 18F, 67Ga, 51Cr, 75Se, 89Sr, 99Mo, 99mTc, 103Pd, 111In, Iodine (123I, 125I, 131I),153Sm, 201Tl, 133Xe
• Naturally occurring radioactive materials (NORM): 40K, 138La, 226Ra, 232Th and daughters, 238U and daughters
• Industrial radionuclides: 57Co, 60Co, 133Ba, 137Cs, 192Ir, 226Ra, 152Eu, 22Na, and 241Am
Operating Conditions
The instrument shall function correctly at temperatures from –20 ºC to + 50 ºC.
The instrument shall function correctly over the range of relative humidity up to 93% RH at 35 ºC.
Quantity: Initial order quantity: 9
Quality Standards: The spectroscopic pager must adhere to industry standards for accuracy, reliability, and performance. Compliance with relevant safety regulations and certifications is mandatory.
Delivery Schedule: Delivery required within 60 days of awarded contract. Supplier to provide estimated delivery dates for confirmation.
