Human olfactory glands do not have receptors for Radium. (Having an odor depends on the human's ability to perceive and odor)
Odour means bad smell. Odour (American spelling odor) just means smell. A bad odour would be a bad smell.According to the Princeton online dictionary:olfactory property: any property detected by the olfactory systemsmell: the sensation that results when olfactory receptors in the nose are stimulated by particular chemicals in gaseous form; "she loved the smell of roses"the description of a smell
B2 receptors
beta receptors
Substances that change their characteristic smells with acid and base are known as olfactory indicators. For example: Onion, Vanilla.
In vertebrates the olfactory receptors are located in the cilia of the olfactory sensory neurons. In insects olfactory receptors are located on the antennae and other chemo sensory organs.
Olfactory receptors detect smells, and gustatory receptors detect tastes.
The sensory receptors for your nose is the semicircular canals and the cochlea
Chemoreceptors
The smell receptors are called olfactory nerves
Olfactory receptors

cillia
Olfactory tracts
The receptors of the eye are photo receptors, the ear has auditory receptors, the nose has olfactory (smell) receptors, the skin has tactile (touch)and thermo- (temperature) receptors and the tongue has gustatory (taste) receptors.
Nasal Cavity
bind to receptors in olfactory cilia.
