Electromagnetic radiation such as UV, gamma or X-ray adds energy to the material in electronics. This energy can cause the material of the components of the electronics to degrade rapidly by causing electrons to move to higher energy level orbits or simply cause the material molecule to break up.
Despite their low-power, relative to current battery technologies, the life-time of these diamond batteries could revolutionise the powering of devices over long timescales. Using carbon-14 the battery would take 5,730 years to reach 50 per cent power, which is about as long as human civilization has existed.
Radiation can ionize the filament but at the level of full shutdown it would most likely be lethal immediately to a person, if you continue to watch they do ratchet the light back down and it turns on.

Long-term or high-dose exposure to radiation can harm both living and nonliving things. Radiation knocks electrons out of atoms and changes them to ions. It also breaks bonds in DNA and other compounds in living things. A single large dose of radiation can burn the skin and cause radiation sickness.

Single-event upsets (SEU) or transient radiation effects in electronics are state changes of memory or register bits caused by a single ion interacting with the chip. They do not cause lasting damage to the device, but may cause lasting problems to a system which cannot recover from such an error.
Radiation harms humans by killing cells and damaging our DNA (which can cause the replication errors that cause cancer). Machines are obviously not affected in that way, but radiation can damage their electronics.

Ionizing radiation is generated through nuclear reactions, nuclear decay, by very high temperature, or via acceleration of charged particles in electromagnetic fields. Natural sources include the sun, lightning and supernova explosions.
Radioactive sources are used to study living organisms, to diagnose and treat diseases, to sterilize medical instruments and food, to produce energy for heat and electric power, and to monitor various steps in all types of industrial processes. Tracers are a common application of radioisotopes.
X-rays, discovered by Wilhelm Roentgen, are a form of electromagnetic radiation. On the electromagnetic spectrum, these invisible rays fall between gamma rays and ultra violet light (Figure 1). They penetrate materials human eyes cannot see through. And x-rays have short wavelengths and high frequencies.
“A laptop's hard drive is safe to put through an airport security X-ray scanner. While an airport security X-ray scanner is “safe” if you take your laptop through a metal detector or if it is examined with a metal wand, you could be at risk of losing the hard drive.
Taking a laptop, hard drive, flash media, or magnetic media through metal detectors, such as those at airport security checkpoints, can cause permanent damage. We strongly recommend you back up all data on your computer before travelling by air.
The conveyor belt carries each piece of baggage through the X-ray beam, and on the opposite side of the tunnel, a detector measures the amount of radiation which has penetrated the scanned item. Dense substances, such as lead, absorb the most radiation, blocking the X-rays' progression”, explains Mikko Halonen.
However, X-rays do not damage or destroy electrical equipment or data. This document contains information about X-ray machines. Taking a laptop, hard drive, flash media, or magnetic media through metal detectors, such as those at airport security checkpoints, can cause permanent damage.
You should not carry your laptop through metal detectors because of the strong magnetic pulse these detectors create. Security wands create the same magnetic pulse and can also damage your laptop. All laptops must be removed from their cases, since the case without the laptop must be x-rayed as well.

The li-ion battery disadvantages include: Protection required: Lithium ion cells and batteries are not as robust as some other rechargeable technologies. They require protection from being over charged and discharged too far. In addition to this, they need to have the current maintained within safe limits.
The quick answer is no, it's designed to be left on the charger. The battery will last longest if you always charge it very slowly, keep it at a cool temperature, and never completely charge or discharge it. Actually, the degradation is probably worst when it's fully charged.
Storing large amounts of energy, whether it's in larger rechargeable batteries, or smaller disposable batteries, can be inherently dangerous. The causes of lithium battery failure can include puncture, overcharge, overheating, short circuit, internal cell failure and manufacturing deficiencies.
- check the voltage now. If it is above or below the normal limits, it could be bad.
- Charge the battery in a good charger. Check the voltage and the temperature.
- After charging check voltage if within spec for a fully charged battery. Place the now fully charged batteries in a cool place, preferably also fireproof.
Batteries left too close to a heat source—or caught in a fire—have been known to explode. Other external factor can cause a lithium-ion battery to fail, too. If you drop your phone too hard (or too many times), there's a chance you'll damage the separator and cause the electrodes to touch.
A huge study that said mobile phone radiation was “cooking sperm” found a big link between using a mobile phone while it is charging and higher radiation. So a low battery isn't necessarily a cause of high phone radiation.

The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again.
The lithium carbonate extraction process harms the soil, and can cause air pollution. There are also concerns around how to recycle it. Eco-nonprofit Friends of the Earth notes that lithium recycling is fraught, as the metal is “toxic, highly reactive and flammable.”
