A chemical dosimeter comprising:
- a chamber defined by a heat resistant mesh;
- and
- a quantity of an adsorbent contained within the chamber;
- the arrangement being such that gas may diffuse into the chamber through the heat resistant mesh so that chemicals in the gas may be adsorbed by the adsorbent.
A dosimeter according to claim wherein the heat resistant mesh is capable of withstanding temperatures in excess of about 250° C.
A dosimeter according to claim wherein the entire dosimeter is heat-resistant.
A method of providing an indication of the quantity of a chemical in a gas, the method comprising the steps of:
- providing a chamber defined by a heat resistant mesh;
- placing a quantity of an adsorbent within the chamber;
- placing the chamber in a region of the gas, so that the gas diffuses into the chamber through the heat resistant mesh;
- and
- analysing the adsorbent to determine the quantity of the chemical that has been adsorbed onto the adsorbent.
