how dangerous are those new bluetrack laser mice ?

like the Microsoft Wireless Mouse 5000 MGC-00001 are those realy dangerous it has no on or off button the moment you put in a battery it turns on without warning immediatly shining the dangerous laser at you on the box it says you will be exposed to radiation how and why would they sell the mouse if your gonna be exposed to radiation ?

if you have this mouse please let me know what you think of this did you read all of the instructions on the warnings those other optical mice without laser are not as dangerous ?

this mouse seems very dangerous to people that have children as they may accidently knock it over or grab it an point the laser at you giving you a mega dose of radiaiton

Short answer for : Microsoft BlueTrack mice are not "dangerous lasers." BlueTrack uses a broad, diffused blue illumination and a specialized image sensor to track surfaces — the beam is deliberately much wider than a focused laser spot, and independent technical coverage describes the source as incoherent blue light rather than a coherent laser. Microsoft press release (Ars Technica analysis).

How that matters for safety: laser products and lamp/LED products are evaluated under different rules. Consumer laser products are regulated by FDA/IEC laser classes (Class 1, 2, etc.) and are generally low-power; LEDs and similar broad light sources are assessed under the photobiological safety standard (IEC 62471). Both frameworks exist to keep everyday devices, including mice, within safe exposure limits for normal use. FDA laser FAQ IEC/LED summary (photobiological context).

Why the warning on the box: manufacturers add regulatory labels and safety text and regulators advise common-sense precautions. For children the standard advice is strict — never deliberately aim a light source at eyes and keep small devices out of unsupervised reach — but a BlueTrack mouse emitter is not the same risk as a handheld laser pointer. Practical mitigations for models that power up as soon as a battery is inserted: keep spare batteries stored separately, remove the battery when storing the mouse, place the mouse face-down or cover the sensor with opaque tape when not in use, and follow the product manual and labeling. FDA guidance on laser/toy safety and precautions.

was correct that pointing-device emitters are very low-power in normal mice; the useful clarification is that BlueTrack achieves tracking with a diffused blue illumination (LED-style) rather than a narrow coherent laser beam. For household use the practical risk is negligible; basic precautions (battery removal, supervision of small children) remove virtually all remaining concern.

first all optical pointing devices have low power Laser units in them.they have an effective range of approximately 1/8th inch just enough to reach your mouse pad. By radiation I assume you are referring to the amount produced by Laser excitation,this is so low that it would not register on a radiation detector that is calibrated to exclude normal back ground radiation. That warning on box is put there by company Liability Lawyers. Later---
