Directa Responsum
Quid est detector radiationis LSJ SEED-RA?
LSJ SEED-RA est alarma portabilis radiationis nuclearis fabricata a Beijing LSJ Technology Development Co., Ltd. Hoc instrumentum crystallum scintillationis CsI(Tl) cum photomultiplicatore silicio (SiPM) coniungit ut radios X et gamma (30 keV usque ad 3 MeV) detegat, velocitates dosis metitur ab 0,01 µSv/h usque ad 100 mSv/h et dosim cumulativam usque ad 9999 mSv, respondet intra minus quam 5 secunda (optime in 2 secundis), et usorem per signa auditibilia, visualia et per telephonum mobile per Bluetooth monitum praebet. Pondus eius non excedit 50 g; habet certificatum IP67 et plus quam 100 horarum statum stand-by reicibilem; idoneum est ad opes in casibus urgentibus, ad responsum ad incidentia chemica, ad inspectionem ambientis radiologici, ad supervisionem plantarum nuclearium et ad examina securitatis.
Cur Monitoratio Personalis Dosis Deficit Sine Alarma Portabili
In radiological operations, the dose a worker actually receives is determined in the first minutes on site, long before a badge is read back at base.
- Area monitors remain at the perimeter — the worker walks away from the instrument, and the instrument stops protecting them.
- Passive dosimeters record dose but never warn — an overexposure is discovered hours later, after the shift, when prevention is no longer possible.
- Bulky survey meters occupy a hand — a rescuer working on a debris pile cannot hold a meter, a tool, and a radio simultaneously.
SEED-RA vs Passive Dosimeter — Side by Side
The comparison procurement teams ask for first: what does a wearable alarm add to the badges a team already carries?
Comparison based on the operating principles described on this page: the SEED-RA alarms in under 5 seconds, while passive dosimeters are read back after the shift.
Detection Performance in a Wearable-Sized Body
Laboratory-grade detection, pocket-size body
CsI(Tl) scintillator plus SiPM detector. The SEED-RA uses the same detection physics as laboratory-grade counters — a thallium-doped caesium iodide crystal coupled to a silicon photomultiplier — achieving highly sensitive detection in a device small enough to forget on a vest. It resolves dose rates from 0.01 µSv/h (natural background) up to 100 mSv/h, tracks cumulative dose to 9999 mSv, and holds relative intrinsic error within ±15% at the Cs-137 reference.
The built-in display shows the live dose rate together with a battery gauge and three status LEDs, so the wearer confirms the reading at a glance without a phone or a console.

Clip-on gravis 50 g quod evanescit in vestitu
Non ultra 95 × 30 × 20 mm et 50 g, bateriam inclusam , SEED-RA vere habet dimensiones aptas ad indendum. Corpus integratum ultrasonicum efficit superficiem exterius levem et hermeticam, et facies anterior ostendit display velocitatis dosis in tempore reali, signum radii trefoleum et tres LEDs virides status quae confirmant operationem normalem e longinquo.
Figura: Visus anterior SEED-RA LSJ — corpus parvum ut in tasca, 95 × 30 × 20 mm, cum display velocitatis dosis in tempore reali et tribus LEDs viridibus status.
Tres canales allarmis: auditivus, visualis et per phonum
Cum velocitas dosis crescat, SEED-RA excitat monitio auditiva et a * allarmem visualem in suis LEDs, deinde transmittit allarmem ad gestorem telephonum mobile per Bluetooth . Supervisor unus, qui singula instrumenta membrorum turmae coniungit, statim videt situationem ultra normam — etiam si ipse detector sub vestibus protectoribus aut in tasca latet. Escalatio alarmis pluridimensionalis est ex proposito, itaque unum tantum obstruens canalem numquam silentium adhibet ad monitionem.

Plus quam 100 horarum in statu expectandi, deinde in charge-er pone
Designum consumtionis parvae energiae tenet SEED-RA in statu expectandi plus quam 100 horarum — plus quam quattuor dierum promptitudinem continuam una in replectione. Replectio per contactus magneticos pro replectendo fit magneticos contactus pro replectendo in basi: nulli foramina aperta, nihil quod cum gantibus inserere oportet, nihil quod pulvis aut aqua adgredi possit. Inter vices unitas rursus in charge-er ponitur et ad plenam promptitudinem redit.

Quaestiones Frequentes — LSJ SEED-RA
Direct answers to the questions that procurement teams and safety officers ask before placing an order.
Q: Which types of radiation does the SEED-RA detect, and by which technology?
A:It detects X-rays and gamma rays using a CsI(Tl) scintillation crystal coupled to a silicon photomultiplier (SiPM). Its energy response covers 30 keV to 3 MeV, with energy response error within ±20%, and relative intrinsic error within ±15% at the Cs-137 reference source.
Q: What dose ranges can the SEED-RA measure?
A:The dose-rate range is 0.01 µSv/h to 100 mSv/h; the cumulative dose range is 0.01 µSv to 9999 mSv. The lower limit resolves natural background radiation levels, while the upper limit covers severe radiological incidents.
Q: How quickly does the SEED-RA respond to a change in radiation?
A:Response time is under 5 seconds—and as fast as 2 seconds—depending on the energy level. This rapid response transforms the device from a dosimeter into an alarm.
Q: How does the SEED-RA alert its wearer?
A:Per tres canales: un allarmum auditivum, un allarmum visibile super LED del dispositivum, et un allarmum telephonicum relatum per Bluetooth. Qui portat dispositivum audit illud, videt indicatores suos, et accipit allarmum in telephono coniuncto.
Q: Quam diu durat batteria, et quomodo unitas replectur?
A:Tempus in statu expectandi est ultra 100 horas propter conceptionem consumi parvi energiae. SEED-RA replectur per contactus magneticos replectionis in basi sua, sine portibus apertis in carcasse.
Q: Estne SEED-RA idoneus ad asperas conditiones in campo?
A:Ita. Carcassa habet gradum IP67 — impervia ad pulverem et aquam — et unitas operatur ab -20°C usque ad 50°C ad umiditatem relativam usque ad 95% (ad 30°C, non condensans), amplectens operationes extramuralis et industriales.
Q: Quomodo SEED-RA portatur dum operatur?
A:Dimensiones non excedunt 95 × 30 × 20 mm, et pondus est 50 g, inclusa batteria; adnectitur cingulo, vesti, aut tasca per clippum integratum in parte posteriori, manibus utrisque liberis ad opus salvatorum vel inspectionis.
