1. A radiation-emitting device, comprising
a. at least one radiation source configured to emit radiation of at least one wavelength towards a target, the target comprising a body having a head section and a foot section;
b. at least one space or surface configured to place the target therein or thereon;
wherein the radiation-emitting device further comprises:
c. at least one dual heating and cooling system configured to heat or to cool the at least one space or surface and comprising
at least one Peltier device, said Peltier device comprising at leasttwo cuboids made of two semiconductor materials having different electron densities, said at least two cuboids being placed thermally in parallel to each other and electrically in series, interconnected with thermally conducting metal bridging plates and sandwiched between a non-conducting material reduced temperature cover plate and a non-conducting material elevated temperature cover plate and configured to be supplied with DC electric current via electrical connections;
at least one first heat exchanger thermally connected as a heat source to the Peltier device's reduced temperature cover plate;
at least one second heat exchanger thermally connected as a heat sink to the Peltier device's elevated temperature cover plate;
at least one fan or fan assembly configured to cause environmental air to flow along the at least one first and/or second heat exchanger;
a first nozzle and a second nozzle configured to pass and direct the environmental air flow having passed the at least one first and/or second heat exchanger and thereby heated or cooled towards the at least one space or surface configured to place the target-or the subject therein or thereon, wherein the first nozzle is configured to pass and direct the environmental air to flow towards the head section of the body and the second nozzle is configured to pass and direct the environmental air to flow towards the foot section of the body; and
at least one circuit board configured to control the DC electric current supply to the Peltier device.
