Radio activity never stops. Radioactive material emits radioactive rays for ever. How ever it can be capped but when ever the material is exposed it will start emitting gamma and Beta rays.
Oh, dude, photons are like the rockstars of the Sun, cruising through the radiative zone at the speed of light. It takes them about a million years to make their way from the core to the convective zone. So, you know, just your average cosmic commute.
A thick, pasty, hazardous material used for lubrication is called industrial grease. This substance is designed to be a long-term solution for heavily used piece of equipment.
The symptoms caused by exposure to a hazardous material vary greatly depending on:what the hazardous material iswhat kind of exposure is involved (inhalation, skin contact, etc.)how intense the exposure ishow long the exposure isIt is not possible to say more unless a particular material and type and duration of exposure is specified.
Garbage as long as it's solid.
Depends on what the material is, and if the person has completed hazard training for that material, and the operation to be performed.

A safe place approved by the government where you can park a vehicle carring explosive for a long time without any worries.
50-200 years, depending on the can material and the environment.
There is a choking hazard for children under 3 years of age. They are safe for older children as long as they are used according to the manufacturers recommendations.
Chest freezers are not hazardous as long as you use them as they are specified to be used. If you accidently dropped it and one of the components inside it broke then it could become hazardous.
Silica Gel packets can be thrown away in the trash. They are not toxic and will not harm the environment, unless they have come in contact with a hazardous substance, which is rare in typical household applications.
In the Sun's radiative zone, energy is transferred through radiation, where photons are absorbed and re-emitted by particles, taking a long time—up to thousands of years—to reach the outer layers. In the convective zone, energy transfer occurs via convection, where hot plasma rises to the surface, cools, and then sinks, creating a continuous cycle that efficiently transports energy to the Sun’s surface. This combination of radiative and convective processes ensures that energy generated in the core eventually reaches the surface, where it can radiate into space.
