sealed radioactive source means the radioactive isotopes which is encapsulated with a stainless steel to avoid higher LET radiation condamination .typically source may be used in brachytherapy to treat the cancer and unsealed source used to in nuclear medicine which is the radioactive source is not sealed examble IODINE131
Sealed Source
Vacuum-sealed clothes are not heavier than unsealed clothes; in fact, they are often lighter because the vacuum sealing removes air and compresses the fabric. This compression reduces the volume but does not change the actual weight of the clothing. Therefore, while vacuum-sealed clothes take up less space, their weight remains the same as when they are unsealed.
The M43A1 detector contains a small amount of radioactive material typically in the form of a sealed radioactive source, such as cesium-137 or americium-241. This radioactive material is used to generate radiation for detection purposes in the detector.
Yes. A radioactive standard is a configuration of radioactive material constructed in a precise way, allowing the standard to be used as a reference when measuring other radiation sources. Standards typically come as solids trapped in a mylar foil pocket, embedded directly in a plastic or electroplated onto a metal disc, or as a sealed liquid solution. Standards are used to calibrate radiation measuring equipment.
uranium is probably the source for radioactive isotopes derived from nuclear reactors
it is unsealed
Sealed Source
A point source device that emits radiation without actively dispersing radioactive material across an area is commonly referred to as a sealed radiation source. Such sources are contained within a sealed casing or structure that prevents the escape of radioactive material.

Sealed bike bearings offer better protection against dirt, water, and debris, leading to longer lifespan and smoother performance compared to traditional unsealed bearings.
Devices that include any point source that emits radiation without actively dispersing radioactive material across an area are considered sealed radiation sources. These sources are contained within a sealed container or device, preventing the spread of radioactive material.

A sealed bottom bracket generally offers better protection against dirt, moisture, and debris, leading to improved longevity and reduced maintenance compared to unsealed options. While unsealed bottom brackets can be lighter and easier to service, they are more susceptible to environmental damage. Ultimately, the choice depends on riding conditions and personal preferences regarding maintenance and weight. For most riders, sealed bottom brackets are often the preferred option for their durability and reliability.
