Nuclear Fusion

A chain reaction refers to a process in which neutrons released in fission produce an additional fission in at least one further nucleus. If each neutron releases two more neutrons, then the number of fissions doubles each generation. …

Nuclear fission: In nuclear fission, an unstable atom splits into two or more smaller pieces that are more stable, and releases energy in the process. The fission process also releases extra neutrons, which can then split additional atoms, resulting in a chain reaction that releases a lot of energy.

Transmutation is a chemical reaction in which nucleus of the atom undergoes a change by radioactive decay and thus result into formation of new nucleus.

Gamma rays

Radiation is energy, in the form of particles or electromagnetic rays, released from radioactive atoms. The three most common types of radiation are alpha particles, beta particles, and gamma rays.

Steps to Reduce Radio Frequency (RF) Exposure

1. Reduce the amount of time spent using your cell phone.
2. Use speaker mode, head phones, or ear buds to place more distance between your head and the cell phone.
3. Avoid making calls when the signal is weak as this causes cell phones to boost RF transmission power.

Effective Protection Specially Against Smart Meter Emf Radiation. The Conductive Fabric Reduce Radiation Pollution from Cell Towers & Cell Phones.

Although this seemingly works only on Android phones. — On your phone open the dialer or phone app. — Now dial *#07# in your phone. This will show the you the SAR measurement of your device as specified by the manufacturer.

USSD Code *#07#: You can check the Radiation level in terms of SAR of your smartphone by dialing a USSD code *#07#, this will show SAR value, if results show SAR below 1.6 watts per kilogram (1.6 W/kg) then it is OK and your smartphone is safe to use otherwise you are advised to change your smartphone immediately.

Overall Winner for Lowest Radiation Smartphone: Samsung Galaxy Note 8 DUOS (SM-N950 / DS) With a SAR of 0.17, the Samsung Galaxy Note 8 with dualism is arguably the lowest radiation smartphone available today in the US.

1.6 W/Kg

SAR values increase as the conductivities of human body tissues increase and usually decrease as the increase of relative permittivities of human body tissues increase. The effect of the dielectric values of human body on SAR is orientation, human body and frequency dependent.

Tilt positions of mobile phone produce higher SAR than that of cheek position due to the reduced distance between helical antenna and human head. Although the body of the mobile phone was directly next to the head, the antenna extrudes far from the head.

In the EU, a SAR value of 2 W/kg has been allowed, while the permissible SAR value in the US is 1.6 W/kg. 1….Choisissez la langue de votre document :

Reducing SAR

1. Avoid or minimize use of high SAR sequences (in the box above).
2. Use Gradient Echo instead of Spin Echo sequences where possible.
3. Reduce initial RF flip angle (α).
4. Increase TR (without increasing # of slices).
5. Decrease # of slices (without reducing TR).
6. Decrease # of k-space views.

While SAR values are an important tool in judging the maximum possible exposure to RF energy from a particular model of cell phone, a single SAR value does not provide sufficient information about the amount of RF exposure under typical usage conditions to reliably compare individual cell phone models.

1.6 watts per kilogram

While there has been a lot of talk about the phones with high SAR (specific absorption rate) value can potentially damage the body at a cellular level, particularly when you hold the phones against your ears and talk on them, not enough attention has been paid by smartphone users to the damage that these devices the …

Specific absorption rate (SAR) is a measure of the rate at which energy is absorbed per unit mass by a human body when exposed to a radio frequency (RF) electromagnetic field.

Specific Absorption Rate (SAR) is the measure of the rate at which energy is absorbed per unit mass by a human body when expose to RF radiations. For phones sold in India, the SAR value should be under 1.6 Watts per kilogram. 91mobiles has compiled a list of the SAR Values of the top 15 smartphones in Q2 2020.

Specific Absorption Rate

Use the speaker phone or a plug in earpiece when you use a cell phone. To protect children from radiation, they should not use cell phones except in emergency and should use the speaker phone. Increase the distance between you and your cell phone whenever it is on, to reduce your exposure to radiation emitted.
