But potassium iodide which is a gas can cause toxic inhalation and so when it is being disposed of you must wear a safety mask. Also as a long term effect it can cause cancer.

How to dispose of a radioactive source: –

The preferred long term approach to the disposal of radioactive waste is geological disposal – which means burying it underground.

The waste is put deep inside suitable layers of rock to ensure no significant quantities of radioactivity ever reach the surface.

A specially engineered underground containment facility is designed so that the natural geological barrier works together with the waste packaging to reduce the escape of radioactivity to an insignificant level.

Why would you dispose of radioactive sources: –

The reason you would dispose of radioactive sources as they are dangerous to human environment and also they could cause sickness and sometimes even cancer.

How would you dispose of benzene: –

What is an agar plate: –

Contamination often occurs when pouring or inoculating agar plates, even when researchers follow proper sterile technique. Bacterial and fungal spores in the air and on surfaces can make freshly poured plates unusable, or can obscure results on inoculated plates. Being able to recognize these contaminants before using a compromised plate can save valuable time.

How to dispose of an agar plate: –

The method used is simple; all you really have to do is just wash it under a hot or cold tap of water.

Why would you dispose of an agar plate: –
