    Radiation from Router

    The abstracts are freely accessible, though. Personally, no. Indirectly, yes.

    Radiation from Router

    I don't know what's "usual", but one can take a look at the literature. There are probably thousands of articles on the topic, so I'm just skimming through a few. Estimates vary, and they would actually depend a lot on the position in which the phone is used (i.e. where the antenna is). On...

    Radiation from Router

    I'm not really interested in straying further from the topic of the thread, but - and I regret to say that - you obviously do not understand what you're talking about, especially when it comes to the science part. There's just so much wrong in so fundamental ways. Do yourself a favor and try...

    Why don't you do a literature search?

    Radiation from Router

    I'm trying to avoid the spread of misinformation, e.g. that the FCC would not stipulate RF safety (demonstratably wrong, see e.g. OET bulletin no. 65), and the fallacy "ionising radiaton==bad, nonionising radiation==harmless". It is not that simple. As a materials science student you should...

    Radiation from Router

    You cannot generalise like that, as it depends, among other things, on the dose. I'm nowhere claiming that radio devices are evil killing machines, but one cannot claim they are completely harmless either. It always depends on a lot of parameters. For that matter, it is equally...

    Perm sec got dressing down.

    So the issue seems to be that this guy didn't secretly stash up his pay in swiss bank accounts, but rather actually spent it openly for something completely legit. To use this against him seems incredibly hypocritical to me. If the civil service doesn't want the leadership/"elite" to spend...

    Radiation from Router

    There is not a single mechanism for mutations. RF exposure can also result in mutations. The most direct effect of RF is heating of tissue, which can knock the biochemistry out of its normal regime, which can potentially lead to mutations as well.

    Perm sec got dressing down.

    Insensitive towards whom? Overpaid politicians whose even more lavish lifestyle may get questioned? (And if they advocate a humble lifestyle, why do they require an obsecenly high pay?)

    Radiation from Router

    Doesn't matter. A microwave oven doesn't use high photon energies, but has pretty devastating effects on biological tissue, and 50 Hz or even DC can kill. There are safety issues with RF energy, but usually not there where people worry most. Classical example, from a post above, is a...

    Radiation from Router

    Even if you're not talking, your handphone keeps communicating with the base station at a reduced duty cycle (unless you turn it off completely). Otherwise, the mobile service provider could not contact your phone for incoming calls/messages.

    Radiation from Router

    Do you have a handphone? Then I wouldn't worry about the wireless router. Handphones radiate much higher power and are much closer to you...

    Is Film Dead?

    The animals contributing to the gelatin emulsion are pretty thoroughly killed. But does anyone know whether the gelatin used for film (and prints) is halal?

    a physics question...

    The question is inherently nonsensical flawed. A ton is a measure of mass not weight.

    NMR-relationship between magnetic field and radio waves

    It is in my answer - the photon energy of the radio wave is resonant with the Zeeman splitting. (Btw, it it is "radio", not "radion".)

    NMR-relationship between magnetic field and radio waves

    The magnetic field splits the energy levels of the I_z=+/- 1/2 spin states of the proton (nuclear Zeeman effect), E=-mu_n*g*B*I_z (where g is the nuclear g-factor, mu_n the nuclear magneton, and I_z the spin component parallel to the magnetic field B). The quantum (photon) energy of the resonant...

    NMR-relationship between magnetic field and radio waves

    If you're talking about magnetic resonance, I am rather familiar with it. But I don't understand your question. Maybe you could ask someone with a better grasp of English to help you formulate it?

    S'poreans ranked lowest

    Why, they are acting on it. Aren't they telling people on almost any occasion that they should keep working instead of retiring? No retirement = no need for retirement funds = problem solved.

    To reduce transmitter's range......

    Beyond privacy reasons, it is only courteous (and good, in some cases mandatory practice) to use minimum necessary power (and thereby reduce interference/RF pollution). Same reason why one should adjust the volume of one's radio/TV set to a level where the neighbours are not forced to listen to...
